The frequency response of an amplifier can be measured by applying white noise to the input and observing the output on a spectrum analyzer. When this was done for a certain amplifier, the display shown in Figure 1.27 was obtained. Find the upper and lower cutoff frequencies (at 3 dB down) and the bandwidth of the amplifier.
