Design a simple circuit that uses a low-pass filter to clean audio signals from a noisy source. Explain your choice of components and configuration.
💡 Hint: Consider what a typical audio signal and noise frequency range would be.
A circuit has a voltage gain of 5. If the input voltage is 1V, what is the output voltage? Additionally, if this circuit has a nonlinear characteristic at extreme inputs, what implications does this have for signal integrity?
💡 Hint: Think about how gain affects output and the definition of linearity as you consider distortion.
