What is digital signal processing system?

Answer 1

DSP -Digital signal processing the word it self says it is process of analyzing the digital signal . The system which does this work of analysis is the digital signal processing system. In this system the raw analog signal(ex:human voice) which is time domain signal is fed to the pre aliasing filter which removes noise part of the signal and this fed to the sampling and quantization in which the real time analog signal is discretized and digitized . After this process this digitized signal is fed to the DSP processor to do the specific operation on the signal (ex: convolution , modulation etc.,) .This processed signal is fed to the D/A which converts the digital signal to the analog signal real time signal. after all explaining the process of signal processing. the stages between the sampling and D/A is the digital processing system.
