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 circuit is a triangle waveform generator that uses as few parts as possible. A 555 timer IC, 2 resistors and two capacitors make the triangle wave. The IC is connected in a 50% duty-cycle astable ...

B&K Precision announced the launch of its 4050 Series, a line of four dual channel function/arbitrary waveform generators. These new instruments can generate waveforms up to 50 MHz for use in ...

In need of a waveform generator for another project, [David Cook] crammed out the old turntable to modify it for a handy hack: By adding a simple reflectance sensor to the pickup he turned it into a ...

A signal generator that can produce the usual sine, square, and triangle waves is handy and has been a staple of electronic benches for decades. Being able to craft custom signals opens up new ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

Are you talking about an inverter? Generators will always make sine waves. Generally speaking, no...there aren't good/cheap filters for a 5.5kw source. The main concern is with motors. Otherwise, you ...
