Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an

Pulse-width modulation (PWM) is used in a variety of electronic situations, such as power delivery and voltage regulation. In electronic music, music synthesizers vary the duty cycle of their audio-frequency oscillators to obtain a subtle effect on the tone colors. This technique is known as pulse-width modulation.
A pulse generator is either an electronic circuit or a piece of electronic test equipment used to generate rectangular pulses. Pulse generators are used primarily for working with digital circuits ; related function generators are used primarily for analog circuits .
Its engineers continued to innovate in IC technology, and remained a significant force. Around 1971, the Signetics introduced the innovative 555 timer IC, which it called "The IC Time Machine". [2] This was the first and only low-cost commercial IC timer available at the time, and soon became a best-seller.
English: Diagram of a monostable circuit made using the 555 timer IC. A low pulse on the trigger line starts the monostable. Date: 23 June 2009: Source: Own work: Author:
The trigger is toggled high when the input voltage crosses down to up the high threshold and low when the input voltage crosses up to down the low threshold. Again, there is a positive feedback, but now it is concentrated only in the memory cell. Examples are the 555 timer and the switch debouncing circuit. [3]
