This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables ...

We’ll do just that and build up a triangle-wave oscillator that can morph into a square wave, passing through a rounded-over kinda square wave along the way.

If you want to get that sound without a fuzz, use equipment that gets that square-wave sound, but with more clarity. “But on 95 percent of what you hear on the [Smashing Pumpkins'} new album ...

For anybody interested, the Big Muff takes square waves and makes the guitar almost sound like a synth. If you want to get that sound without a fuzz, use equipment that gets that square-wave sound ...

Note the resonant peak in the audio band. Figure 2.8: The response of figure 2.7 to the 0-10mA 333Hz square wave. Talk about ringing! Still to come: we'll look at 'real' operational amplifiers (well, ...

Instead, early devices had basic internal speakers that could produce square wave audio — those “beeps” and “boops” that everyone associates with clunky, first-wave computers.
