This simple circuit generates narrow pulses at about 700-800Hz frequency. The pulses, containing harmonics up to the MHz region, can be injected into audio or radio-frequency stages of amplifiers, ...

For a long time, I have thought that pulse generator outputs should not have adjustable amplitude and offset. Instead, they should have an adjustable top value and a separately adjustable bottom value ...

The system in Figure 2 uses the ADF4372 PLL (see Figure 5), a wideband synthesizer with integrated VCO, that allows the implementation of fractional-N or integer-N frequency synthesizers when used ...

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 ...

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 ...

Signal generators are one of the most versatile electronic instruments used, and they can be found in all areas of design, development, production and field tests. Their applications range from base ...

Fujitsu Laboratories has developed a CMOS-based millimeter-wave signal generator capable of modulating its frequencies across a wide band of 76-81 GHz at the world’s fastest speeds. This development, ...
