INTRODUCTION

The impulse response of a dynamic circuit completely characterises it. The zero-state response for any arbitrary input can be obtained by convolving the input function with the impulse response in the time-domain. Non-zero initial conditions, if present, can also be handled by replacing them with impulse sources; however, the impulse response relevant to the corresponding point of application of source should be used.

We found that the sinusoidal steady-state frequency response function of a stable circuit is intimately related to its impulse response. Thus, the frequency response function contains the impulse response in a disguised manner. This prompted us to ask whether we can work out the zero-state response of a stable circuit ...
