A small audio test generator is very useful for quickly tracing a signal through an audio unit. Its main purpose is speed rather than refinement. A single sine-wave signal of about 1 kHz is normally ...

It is possible to generate the German time signal DCF77 at 77.5 kHz, as demonstrated in this article. We feature a PC as ...

Designed for audio product testing, the VP-8192A, -8193A and -8194A AM/FM signal generators feature a bandwidth from 100 kHz to 140 MHz and a 0.1 dB electronic attenuator with up to 126 dBµV output.

Versatile low-cost audio signal generator and pulse generator (up to 4MHz) based on Arduino Nano MCU module. Waveform generators, also known as “function generators”, have been popular DIY projects ...

It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to ...

Are you interested in building a 20kHz 2-channel oscilloscope and a 2-channel signal generator for only $20 with minimal effort? Be sure to check out [Jana Marie’s] Instructable that goes over how to ...

If you need a very pure sine wave in the audio range, the circuit in Figure 1 can help. It is a simple deal: A sine wave with a THD of 1% coming from a function generator that goes through a trackable ...

A common PC sound card can be used as a sine/square/triangle function generator, but the output suffers from limited rail-to-rail swing, plus its zero-centered has no dc offset. This circuit overcomes ...

Leading life-safety equipment manufacturer, C-TEC, has launched an innovative new Audio Signal Generator for testing induction loop amplifiers. Specifically designed to simplify the testing of ...
