What does "Clipping" look like on an oscilloscope, and what causes it?

The top and bottom of the waveform look "flat" or cut off. It happens when the amplifier is pushed beyond its maximum voltage capability.

In an amplifier, what is the "Signal-to-Noise Ratio" (SNR)?

A measure that compares the level of a desired signal to the level of background noise. (The higher the ratio, the cleaner the sound).
