This simple circuit has been designed to generate sine waves with a frequency of 1 KHz while featuring low distortion and low output impedance until 1 V RMS as it obtains power from batteries. Sine ...
The circuit of Figure 1 produces an accurate variable-frequency sine wave for use as a general-purpose reference signal. It includes an 8th-order elliptic, switched-capacitor lowpass filter (IC3) that ...
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 ...
This application note demonstrates nine different circuits that can be used to generate a sine wave. The first, a phase shift oscillator, is shown below. To view the application note, click on the URL ...
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 ...
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 ...
Fellow writer Charles S. “Buc” Fitch penned a multi-part series on backup power generators in the the Feb. 7, April 18, June 13 and Aug. 8 issues of Radio World Engineering Extra. (Read them at ...
