WebSep 13, 2024 · In the lock-in amplifier, the reference signal is multiplied by the amplifier’s input to produce a new output. After adjusting the low-pass filter, a low-pass signal is produced, which corresponds to the reference signal but with all frequencies below the cutoff frequency removed. WebA straightforward analog implementation of an audio amplifier uses transistors in linear mode to create an output voltage that is a scaled copy of the input voltage. The forward voltage gain is usually high (at least 40 dB). If the forward gain is part of a feedback loop, the overall loop gain will also be high.
