According to textbooks, a sine wave is a wave whose form resembles a sine curve. Often in power electronics, we need a sine wave generator for some applications; a dc/ac power inverter, for example.

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 ...

KAWASAKI, Japan--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched a three-phase brushless DC motor control pre-driver IC, “TC78B011FTG,” and started volume ...

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") today announced the launch of “TB67B000AHG,” a new three-phase brushless motor driver for home appliances such as ...

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables, and other ...

Toshiba Electronics Europe has launched a three-phase brushless DC (BLDC) motor control pre-driver IC for motors that require high rotation speeds. Suitable for server fans, pumps, blowers and suction ...

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

I can remember a colleague working for weeks on a sinewave generator board for a piece of test equipment. He came up with a Wein bridge oscillator with several refinements that had wonderfully low ...

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 ...
