{"version":"1.0","type":"link","title":"Pulse-frequency modulation - Newikis","description":"Pulse-frequency modulation (PFM) is a modulation method for representing an analog signal using only two levels (1 and 0). It is analogous to pulse-width modulation (PWM), in which the magnitude of an analog signal is encoded in the duty cycle of a square wave. Unlike PWM, in which the width of…","provider_name":"Newikis","provider_url":"https://newikis.com","cache_age":86400,"thumbnail_url":"https://thumb.wikimedia.org/wikipedia/commons/thumb/2/29/PFM.png/1280px-PFM.png","thumbnail_width":1280,"thumbnail_height":506}
