Circuit testing with a sawtooth:
audio measurements in theory and practice
Many experts in the field query the use of sinewave signals to test amplifiers and other audio gear. Although a rectangular signal is in principle suitable for many measurements, the sawtooth is believed by many to be a much better test signal. The combination of this test signal and an oscilloscope should enable you to give an expert opinion about audio equipment performance.
