Hello Reader,
I was wondering regarding the frequency and amplitude of a signal, viz sine wave. I think the frequency parameter should always specific to voltage.
While defing the frequency responce (analysis) of any device, the basic component considered is a sine wave. Which is nothing but a specific rate of change of voltage withing a given time.
For instance, for a low pass filter, cut-off frequency Fc is defined irrespective of amplitde. So it can pass all frequencies below Fc say with an amplitude V. So if the amplitude of signal is reduced to V', principly the signal of frequency more than Fc should be passed since the rate of change of voltage is less than what was there with earlier signal of amplitude V.
Is that so? In OPAMP theory this term is very weel defined by slew rate but not in any other frequecy terms like cut off frequencies etc.
