The best inverter and battery combos under ₹25,000 for reliable power backup at home or office, with long-lasting performance ...

A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of ...

Researchers have shown that abstract mathematical functions from the frontiers of theoretical physics have a real-world use ...

Everything you wanted to know about (re-)mastering audio, but were afraid to ask. Audio engineers help explain the art and science.

At its core, an oscillator generates sine, square, or triangular waves, which are transformed into other waveforms through wave-shaping circuits. The breadboard prototype demonstrates this ...

Not all UPS devices are created equal. Some are "pure sine wave," which refers to the waveform generated by the power supply. With sensitive electronics, "you're going to want to have something ...

When operating the waveform generator, use the Wave button to select the output waveform: sine, square, pulse, ramp, Arb, noise, and DC. The Mode button lets you set the parameters such as frequency, ...

Simulated sine-wave UPS delivers a stepped, approximated waveform using pulse-width modulation (PWM). That's the same concept used to control PC case fan RPM. These are often far less expensive ...

This circuit can run at way beyond 100kHz, but can’t then be recommended for waveform purity! (By about 25kHz, the tri-wave has turned into a pretty good sine, anyway.) Calibration of a tuning scale ...
