The sine wave, V (t), is completely described by this equation. V a controls its peak amplitude, V o controls the amplitude offset, f controls the frequency, and j controls the phase. When an equation ...

The figure shows a schematic for an oscillator amplitude-control servo system. The circuit creates a closed-loop system that supplies a fixed and adjustable peak-to-peak amplitude ...

A sine wave is a geometric waveform that oscillates periodically and is defined by the function y = sin x.

Consider a complex signal composed of a sine wave and a sinc function as shown in Figure 3. Figure 3. The time domain representation of a complex signal composed of a sine wave and a sinc function.

However, for a sine wave, the only zeros come at 1/2 the frequency. For a cosine wave, the zeros start at time zero and also repeat every 180 degrees.

One application I recently dealt with needed multiple phases of sine waves, all of equal amplitude. I considered 45°, 60°, and 90° differences, but decided 60° was the best solution ...

I have just discovered that Apex Microtechnology of Arizona actually makes a chip, the SWR200 Precision Sine Wave Reference, to do much the same thing, a nice low-distortion sine wave with a ...

We all know that electric utilities in the United States generate electricity at various 60-Hz voltage levels that result in a sine wave waveform. The height, or amplitude, of this sine wave is called ...

Guest columnist Bob Marchetti senior manager of product marketing at Vicor describes how sine amplitude conversion techniques can be used to improve power efficiency of DC-DC converters. Most systems ...
