Abstract :
The advantages of the recursive digital filter as a real-time signal processor are stated, and, as an example, a fourth-order Cheby¿shev lowpass filter has been synthetised and programmed into an online computer. Typical responses are shown for pulse, step and low-frequency mixed sinusoidal signals.
