A cosine curve is graphed similarly to a sine curve, but is out of phase with it. In particular, a sine wave crosses the center line at each interval of pi (π), whereas a cosine wave peaks at ...

An RC phase-shift oscillator is in fact an electronic oscillator that produces a sine wave using a resistor-capacitor phase-shift network. It consists of an inverting amplifier element such as a ...

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 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 ...

Toshiba’s new 600 sine-wave PWM driver IC targets the three-phase brushless motors widely used in home appliances and industrial equipment.

We saw in the last installment that a sine wave and a cosine wave are the same except for phase and you can model them like this: y=A*cos(2πft+Φ). If the phase angle (Φ) is -90 degrees, you ...

Absopulse's FTT Series (three-phase to three-phase frequency converters) is available with output power levels of up to 12 kVA; custom versions provide far higher output power. The company also offers ...

Thus, a second harmonic at a phase difference of 90° with respect to the fundamental in the input sine wave doesn’t contribute to the ADC linearity in the measurement.
