Consider one stage of the amplifier cascade in Fig. P1.37 of the Text. At what frequency is its response 3 dB down from the midland value? For 2 stages in cascade, what does the 3 dB frequency become? For a modified 2-stage cascade in which one of the resistors is decreased to kR (k51), find a process to calculate what the frequency becomes. For what value of k does f y dB of the modified 2-stage 0.95 cascade have a value 2aR ?
