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

Indeed, Signal Processing has been integral in speeding up key engineering projects that require complex mathematical modeling processes to be completed. Our expert DSP Engineers on Freelancer.com are here to assist you with your project no matter the scope. So if you need help with a Signal Processing problem or want advice on improving existing strategies within your organization, you can trust these professionals provide expert advice and results quickly and cost-efficiently.

    Your task is to code an RGB to MIPI DSI pipeline in a Lattice LIF-MD6000 FPGA. The objective is to simply succesfully initialize and show a video output on a specific VR-type MIPI DSI display of which the full datasheet will be provided. The display requires a specific initialization procedure that includes DCS and Manufacturer commands. The display can be used in both 4x2 data lanes or 4x1 data lanes by using Vesa DSC compression. The latter shall be used and a compression layer shall be included in the pipeline. The pipeline shall use as little LUTs and resources as possible, and to do so it shall use the hard d-phy interfaces included in the FPGA. A basic test pattern generator may be used to show functionality for the video output.

    I need a production-ready four-in-one ESC that can comfortably deliver up to 70 A per phase on 6 S and 8 S Li-Po packs. The board must accept either AM32 or Bluejay firmware and talk flawlessly to a Betaflight flight controller over DSHOT. Standard 30.5 × 30.5 mm mounting is fine; there’s no push for an ultra-compact layout, but weight still matters to racers, so keep the copper and heatsinking efficient rather than bulky. Core requirements • Current sensing on each power rail for accurate amperage reporting • Full telemetry output (voltage, amperage, temperature, rpm) back to the FC • Robust MOSFET selection and gate drive to survive 70 A bursts on 32 kHz PWM I’ll need the complete project package: schematic, PCB layout files, cleanly annotated B...

    I’m building a proof-of-concept cognitive radio that can hop intelligently across idle channels in real time. The core of the work is a GNU Radio flowgraph that performs energy-detection sensing on a Universal Software Radio Peripheral (USRP) and then makes dynamic spectrum-access decisions based on the results. Here is what I need from you: • A clean, well-commented GNU Radio Companion file (or equivalent Python blocks) that implements energy detection, computes thresholding adaptively, and flags spectrum holes fast enough for live operation. • A simple access policy module that uses those flags to retune the USRP transmitter/receiver without crashing or losing sync. • A short README explaining key parameters, how to replicate the test, and how to extend the sen...

    I’m looking to modify a DualSense PS5 controller joystick into a true square-gate analog stick for PC play. The job combines both hardware and software changes to achieve a physical square gate that constrains the stick into a square path for the left stick (right stick optional if straightforward), and a matching software solution so Windows interprets the input using square behavior rather than the usual circular normalization. I have a general idea of the goals and constraints, but I’m not an expert in controller internals, electronics, or driver development, so I’m relying on the freelancer’s expertise for the technical implementation. Mechanical side: I’m looking for a custom-fit square restrictor gate designed to integrate cleanly within the existing D...

From post-WWII dumping to modern conflict spillover, these extremely hazardous explosives jeopardize the lives, livelihoods, and environments of nearby communities. UNDP is particularly interested in solutions that can be safely used by members of these communities, empowering them and enabling widespread knowledge of these dangers without requiring military or high-cost commercial interventions.
