The PIC17C42 is equipped with two high frequency Pulse Width Modulation (PWM) outputs. In a pulse width modulated signal the period of the signal is (usually) kept fixed, while the duty cycle is...
OVERVIEW
Baseband modulation techniques encode information directly as the amplitude, width, or position of a pulse. They do not utilize a sinusoidal carrier. Some of these modulation schemes are...
Brushless DC fan (BDC) speed can be varied using pulse-width modulation (PWM). The typical PWM control scheme inserts a power switch in series with the fan, as shown in Figure 1. In such applications,...
Stepper motors are designed to offer an economical method of open-loop motion control. While easy-to-use, they are prone to skipping or stalling resulting in position loss. This application note...
A 3-phase brushless motor requires the amplifier to provide electronic commutation. Commutation of a brushless motor means that the amplifier needs to decide which phase of the motor to energize and...
