[Debraj] needed a simple signal generator for a project he was working on, but didn’t have one handy. He found that the easiest and cheapest way to get clean, reliable signaling was by using ...

A very simple thyristor signal generator circuit which uses a single thyristor, two resistors, a capacitor and a mini-loudspeaker. Once the circuit is switched ti a current source, current flows ...

In this article, we'll discuss how to use a highly-integrated programmable clock generator to address these demanding design parameters. The advantages of using these clocking solutions to reduce ...

[Armeen] — a summer intern at Opal Kelly — did a very interesting open source FPGA-based signal generator using a Xilinx FPGA, and a SYZYGY-compliant digital to analog converter.

I realise diamond buffers have their limitations, but at least they are fast (in modest rf terms) and have good driving capability. All the transistors are on all the time, so there are no delays ...

If your spectrum analyzer lacks a tracking generator, here's a low-cost method for plotting the frequency response of filters, coax cable loss, and other 2-port RF components.
