Digital signal processing (DSP) systems are widely used in medical devices, video processing, telecommunications, and industrial products. Syprosoft has deep theoretical and empirical skills with real-time DSP algorithms and implementation on actual commercial DSP hardware. Trade-offs and optimizations needed to meet execution throughput and resource usage are routinely handled. Algorithms such as FIR filters, IIR filters and FFT have been implemented. Advanced techniques of adaptive filtering, signal detection, echo cancellation, and speech signal processing have been implemented. Descriptions of some sample projects follow.
