Maxim Raginsky Lecture VI: Convolution representation of discrete-time systems More seriously, signals are functions of time (continuous-time signals) or sequences in time (discrete-time signals) that presumably represent quantities of interest. Systems are operators that accept a given signal (the input signal) and produce a new signal (the output signal). Of course, this is an abstraction of the processing of a signal.May 22, 2022 · Operation Definition. Continuous time convolution is an operation on two continuous time signals defined by the integral.
