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 ...

This is a very simple square wave generator circuit built with IC 74LS00 that can generate square signals with frequencies between 20 Hz and 1 MHz. Its stability is good enough for most applications.

What is a high frequency generator circuit? High frequency waveform generator is very useful in electronic experiment and design. This circuit generate sine wave oscillation, but actually we can ...

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 ...

When we use a microcontroller to flip a few GPIOs or talk SPI to a peripheral chip, we are often overlooking that it will usually contain an array of built-in peripherals that were once the preserve ...

Wave power—energy harvested from ocean currents—is likely to be the next big thing in renewable energy generation, so researchers are spending quite a bit of time on new technologies to take advantage ...

Abstract: As a sensorless control method of interior permanent magnet synchronous motors (IPMSMs) at zero and low speeds, high-frequency square-wave voltage injection (HFSVI) method faces the ...

Abstract: When employing high-frequency (HF) voltage signal injection for sensorless control of dual three-phase interior permanent magnet synchronous motor (DTP-IPMSM) under zero- and low-speed ...
