The operation of digital signal processors in continuous time is discussed. It is shown that the main advantages of digital arithmetic can be maintained in such operations, while aliasing of the signal and the quantization error is avoided altogether. Continuous-time operation makes possible a smaller number of bits for a given signal-to-quantization error ratio. Simulation results are presented.
