The frequency response of an amplifier is a graph of voltag

The frequency response of an amplifier is a graph of _____.

Solution

ANS: Output Voltage Versus Frequency.

1)If we consider output as Voltage and keeping input with constant Amplitude and changing input Frequency,then we observe that output voltage changes in magnitude and phase at same input Frequency.

2) This is due to presence of active and passive components in amplifier circuit as depended on Frequency.

3) This type of response is Frequency response.

4)If output is only magnitude considered then it is Amplitude spectrum and If output is only phase considered then is Phase spectrum

5)For Frequency response, frequency is on xaxis and magnitude or phase on yaxis.

6)The analysis of amplifier behaviour with respect to Frequency is Frequency domain analysis and with respect to time is time domain analysis.
