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 ...

Sine-wave generators with 0° to 360° phase-shifts are very important testing blocks in many systems involving DSP operations (i.e., I/Q modulator-demodulator ...

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.

We needed a handheld, battery-powered signal generator with a sine-wave output that was continuously adjustable from 100 Hz to 10 kHz. For such a wide frequency range, we selected a function-generator ...

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 ...

Microcontroller addict [Debraj] decided to make his own programmable sine wave generator, and was able to put it together for under $40 USD. Other than low-cost, his list of requirements was as ...
