In some servo motors, a 20% duty cycle of a 20 ms square wave will rotate the shaft in 180 degrees while a 10% duty cycle will reset it to its original position. PWM duty cycle determines how the servo motor rotates. chuck\u0027s heating vermontIn electronics, duty cycle is the percentage of the ratio of pulse duration, or pulse width (PW) to the total period (T) of the waveform. It is generally used to represent time duration of a pulse when it is high (1). In digital electronics, signals are used in rectangular waveform which are represented by logic 1 and logic 0. Logic 1 stands for presence of an electric pulse and 0 for absence of an electric pulse. For example, a signal (10101010) has 50% duty cycle, because the … chuck\u0027s herrin il
