This audio frequency generator is a triggered signal generator. When a positive pulse of about 6 volts (minimum) is fed to the circuits input , a modulated audio signal comes out of the output. The ...

This article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...

Testing the frequency response of an audio device typically requires a sine-wave oscillator, an ac voltmeter or an oscilloscope, and an operator to record the response of the device at several ...

What kind of clever things could you do with a signal that had a period of 2 hours? Or 20? Any ideas? No seriously, tell us. Because [Joseph Eoff] has come up with a way to produce incredibly low ...
