Hello to everybody,
I would like to generate a sounds collection for people without oscilloscope. What are the most common and helpful testing signals?
I know that the ‘shapes’ are sine, triangle/saw-tooth, square and perhaps inverse line.
But what frequencies? 10hz, 1 kHz, 10kHz and 20kHz?
It should be mono only, or stereo?
Best wishes,
Milan

There is an app for that. Several apps for the iPhone and iPad have good signal generators.
The only kind of signal that will be useful without an oscilloscope is a sine wave. Sine wave amplitudes can be measured with a simple multi-meter to check signal path integrity and amount of gain.

Scopes can be very cheap, even free on your phone. However, your phone may not be as good as the DUT.
