Question

An audio amplifier has a low-corner frequency, $f_{\mathrm{LO}}$, of $100 \mathrm{~Hz}$, and a bandwidth of $15 \mathrm{kHz}$. The amplifier has an input voltage of $20 \mathrm{mV}$ and an output voltage of 6 volts. Plot the frequency response (frequency on a log scale) of this amplifier showing the midband gain in decibels, the two corner frequencies, and the bandwidth.

Step 1

We have: - Low-corner frequency, \( f_{\mathrm{LO}} = 100 \, \text{Hz} \) - Bandwidth = \( 15 \, \text{kHz} \) - Input voltage = \( 20 \, \text{mV} \) - Output voltage = \( 6 \, \text{V} \) Show more…
