The overall voltage gain of cascaded amplifier stages is the product of the volt

Question

The overall voltage gain of cascaded amplifier stages is the product of the voltages and currents gain of the individual stages. True or False What Mathematical technique it utilized for finding the amplitudes, frequencies and phases of the components of a given waveform? A. Superposition B. Laplace Transformation C. Fourier Analysis D. Signal Processing E. No correct answer Which of the following is not true about ideal operational amplifiers? A. infinite input impedances B. Infinite gain for the differential input signal C. Zero gain for the common mode input and output signals D. Infinite bandwidth E. None of the above

Explanation / Answer

4)the over-all voltage gain of cascade amplifier is individual stages of amplifier,not the product of the voltages and currents gain of the individual stages.so given statement is false

5)fourier analysis technique is utilized for finding the amplitudes,frequencies and phases of the components of a given waveforms

6)infinite gain for for the differential input signal is not true about ideal amplifiers,exept option B

remaining A,C,D options are related to ideal operational amplifiers
