A description of a four-phase RC oscillator of a sinusoidal and rectangular shape is given. A triangular-shaped signal is obtained by the counterphase addition of half-waves of sinusoidal signals ...

Unlike digital RF generators that produce only sine waves, function generators can produce repetitive waveforms of different shapes such as sine, square, triangular, sawtooth, and pulse. Function ...

Anyone searching for a function generator may be interested in a new DIY Arduino project which details how you can make your very own. “A function generator is a very useful tool, especially when we ...

It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina Neumryr]’s niche comes in building projects from old electronics magazines, and ...

A former coworker friend sent me a Tektronix 3-slot mainframe and several plug-in modules (Fig. 1). The TM500-series mainframes are 1970s vintage, but like a lot of old test equipment, can still work ...

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 ...

The new R&S SMB100B analog microwave signal generator from Rohde & Schwarz offers analog signal generation up to 40 GHz in the midrange class. This signal generator features a signal purity which ...

The TG550 from TTi (Thurlby Thandar Instruments) is a 5MHz function generator incorporating a digital frequency locking system. The firm claims this gives the generator a level of frequency stability ...

I don’t have a signal generator, or more specifically I don’t have a low frequency signal generator or a function generator. Recently this fact collided with my innocent pleasure in buying cheap stuff ...
