In this modulation, the signal is sampled at regular intervals and each sample is made proportional to the amplitude of the modulating. Graphical user interface was design to download the generated spwm modulations to the control device allowing starting and braking. Other duty cycles produce any voltage in the range of 0 to 100. Introduction to pulse width modulation pulse width modulation pwm is a technique in which a series of digital pulses is used to control an analog circuit. Pulse width modulation is used in a variety of applications including sophisticated control circuitry. Discover everything scribd has to offer, including books and audiobooks from major publishers.

In all the above cases, we detect the message of the pulse modulated signal and reconstruct the original analog signal.
