Abstract
Frequency independent analysis is based on a simple assumption that the circuit is capable to accept and process signals whose frequency spectrum includes all frequencies, from minus infinity to plus infinity. Nonetheless, we already know that elements capable to store energy need a finite amount of time to change their internal states. For slow changes this time delay is negligible, thus “low frequency” approximation produces acceptable results. However, as the signal frequency increases, the impedances of frequency dependent components drastically change.
