See modulation for a sound example. Amplitude modulation spectrum of two sine waves, carrier C and modulator M, showing the addition of a pair of sidebands, C + M and C - M, around the carrier. The ...

Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...

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 communication, phase ...

Figure 1 illustrates the principle of sinusoidal bipolar pulse-width modulation. The figure shows the associated waveforms where a sinusoidal signal (V sine) serves as a reference and a triangular ...

Toshiba’s Hall sensorless sine-wave drive three-phase brushless DC motor control pre-driver IC helps reduce vibration and noise of high-speed motors.

Sine-wave motor control IC and IGBT (rating of 600V/2A) are integrated in a single package. This reduces the size of mounting area and board layout, and contributes to overall system cost reduction.

Absopulse Electronics FTT 3K Series has introduced a rugged, modular AC/AC frequency converter system that uses microprocessor controlled, high frequency PWM technology to deliver 3-Phase, 3000 VA ...
