In Fig. if the CMRR of the operational amplifier is 60dB, then the magnitude of the output voltage is

In case of class A amplifiers, the ratio (efficiency of transformer coupled amplifier)/(efficiency of a transformer less amplifier ) is

(a) Specify the type of the negative feedback in the JFET amplifier shown in Fig.
(b)Calculate the voltage gain (V₀/V_i), of the amplifier with no feedback (R_f=$$\infty $$).
(c)Determine the value of the resistance R_f, required to give a voltage gain (V₀/V_i), or - 10.

A rectangular pulse existing between t = 0 and t = T and having an amplitude A is to be received by a matched filter

(a) Draw the impulse response of the matched filter labeling all important points and the axes.
(b) Find the signal shape at the filter output. Lable all important points and axes.
