arun kumar vtu notes for signals and systems

The goal of this series is a principles-based capability to design signal-processing architectures to convert signals between various forms. Signals are continuous-time or discrete-time, real or complex, and baseband or passband. Operations used on those signals include analog filtering, digital filtering, interpolation, decimation, and frequency shifts. The approach is rigorous but largely graphical with little explicit mathematics.
