Signal Processing is the art of transforming different kinds of signal (sounds, images, videos, etc.) into a lattice of information that can extracted and applied in many different ways. Digital signal processing (DSP) considers both technological aspects, such as the study of algorithms, and conceptual aspects; it makes the virtual world closer to the physical world. It is used to transform data into useful information for state-of-the-art machine learning models, a growing area for many businesses for decision support and predictive analytics. This work is made possible by DSP Engineers that know how to capture and process signals from both physical and virtual sources.

Signal Processing Engineers are experts in both the technology and algorithms that enable data analysis. They are able to program efficient applications for sensory processing as well as devise effective strategies for storage repository of data. Furthermore, they streamline complicated engineering processes within organizations such as creating mathematical modeling systems or addressing specific modelling problems with meaningful input-output relationships related to their areas of expertise: electroencephalogram (EEG), electrocardiogram (ECG), medical devices and development.

Here's some projects our expert DSP Engineer made real:

  • Improving accuracy of machine learning models by fine tuning signal processing code written in C++
  • Utilizing Transformers for EEG-based motor imagery recognition
  • Analyzing signals and performing Fourier Transform routines in MATLAB/Octave/SCILAB
  • Developing Bandpass filters in C++ for data clustering
  • Remote debugging using matlab for eeg signal processing
  • Extracting features from EEG signals to detect emotion synchronization between a mother and an infant
  • Cleaning Time Series Data with columnwise smoothing in Python Panda

    I’m working with a Diode Laser Board and I need a custom receiver that can plug into that setup, track the machine’s positioning in real time, and instantly flag any faults it detects. The idea is to have continuous monitoring so I can see where the laser head is at any moment and receive automatic alerts if something drifts out of spec or a component misbehaves. Ideally, the receiver will take positioning data straight from the board, process it with minimal latency, and expose a simple interface—serial, USB, or another protocol you recommend—so the data can be displayed live on a host PC or microcontroller dashboard. Reliability is critical, so built-in error detection should cover signal integrity, unexpected motion, and any other obvious fault conditions you id...

    I want a LabVIEW-based curve tracer that mirrors the behaviour of the Digilent WaveForms instrument but runs entirely inside LabVIEW while talking to my Analog Discovery 2. The program must sweep a user-defined voltage across a device, sample the resulting current and voltage, and plot the I-V curve in real time. Primary test focus is on resistors, yet it should also cope with simple LED measurements so the code isn’t locked to a single device type. Please make the sweep limits and step size configurable so I can adapt quickly to different resistor values or LED forward voltages. The interface needs to feel as quick and informative as WaveForms, with one extra twist: I need reliable data-export options (CSV at a minimum) straight from the GUI so I can toss results into Excel or...

    I have a piezo-based wet/dry sensor concept that relies on tracking resonance changes in a PZT ceramic between 20 kHz and 500 kHz. When the tip is in air the vibration is high-Q with a large voltage swing; when any liquid covers it the amplitude drops, the Q-factor falls, and both phase and resonant frequency shift. I now need an electronics specialist who can turn this working principle into a repeatable, field-ready solution. The job covers selecting the drive topology, designing the analog front-end, and implementing a small digital section that continuously excites the ceramic, samples the returning signal, and decides “wet” or “dry” in real time. Accuracy, low noise, and robust thresholding against temperature or viscosity changes are essential. Delive...

    I am building a free-space optical communications platform and need a complete pointing, acquisition, and tracking software package that can consistently maintain sub-degree alignment between my optical terminal and a remote node. Core expectations • Pointing accuracy: better than 0.5° under nominal environmental conditions; 100% uptime once locked. • Communications interface: native Ethernet/IP for command, telemetry, and reporting status. • Platform: x86/Linux preferred; however, I can compile on other POSIX systems if the code is portable. Your solution should include: 1. Real-time control loop that accepts attitude sensor data (e.g., IMU, encoders) and drives two-axis galvanometers and a MEMs array. 2. Acquisition logic capable of coarse scan, fine sc...

    I have an ultrafast-laser–written waveguide already modelled in RSoft (the .dat structure file is ready), yet every attempt to launch light through it in BeamPROP ends with complete loss of signal. I need an RSoft specialist who can open my file, set up the correct input field and boundary conditions, run the propagation and show where the power is disappearing. Your task will be to: • Configure the launch conditions so the field actually couples into the guide. • Optimise any parameters necessary in geometry or materials to remove the loss of signal (mode mismatch or other distortion could be contributing). • Deliver screenshots, the corrected RSoft project file and a brief note explaining what you changed so I can reproduce the result. When you reply, focus...

    I need robust, well-documented firmware that lets an ESP8266 on the Arduino platform both send and receive infrared commands for multiple air-conditioner remotes. Serial command-line interaction over USB or Telnet is all that’s required; no web or mobile interface is necessary. Core tasks • Build or adapt an Arduino-compatible sketch that scans incoming IR frames, decodes them, and logs the raw timing as well as the decoded protocol and data. • Implement a complementary routine that allows me to replay captured frames or craft new ones from the command line, then transmit them through an IR LED with correct carrier frequency and timing precision. • Structure the code so adding or tweaking protocols is straightforward—I will be experimenting with a variet...

    Description I am looking for someone experienced in EEG data analysis using MATLAB and FieldTrip to provide analysis support for a university research project investigating the effects of attentional load on multisensory integration (MSI). I have already completed data collection and have the raw EEG data in BrainVision format (.eeg, .vhdr and .vmrk) for multiple participants. The experiment includes auditory (A), visual (V) and audiovisual/bimodal (AV) stimuli. Participants also completed an N-back manipulation involving 0-back, 1-back and 2-back conditions, which is being used to manipulate attentional/cognitive load. The overall aim is to investigate whether multisensory processing/integration changes depending on attentional load, using behavioural and EEG measures. I am looking f...
