SUMMARY
The discussion centers on calculating the input signal amplitude when a microphone with an output impedance of 1 kΩ is connected to an amplifier circuit. Given that the microphone produces a maximum amplitude of 5 mV and the oscilloscope has an input impedance of 1 MΩ, the input signal amplitude will be affected by the impedance matching. The gain formula, Gain = R2/R1, is relevant for determining the amplification in the circuit. The input signal amplitude will be lower than 5 mV due to the impedance mismatch between the microphone and the amplifier.
