Analog Signal Processing is essential even for a digital system that has an analog signal as input. Analog Signal Processing: Analysis and Synthesis is a textbook for advanced undergraduate and graduate level students as well as circuit designers. It is addressed to Electrical, Electronic Engineering students and practicing engineers interested in instrumentation system design and in understanding the analysis and synthesis of signal processing in analog domain. A basic knowledge of analog circuits is desirable but not essential.
