WebExample 1: Special case, Duty Cycle = 50% Example 2: Special case, Duty Cycle = 40% Even Square Wave (Exploiting Symmetry) Even Square Wave (Exponential Series) Even Triangle … In 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 …

WebThe series of square wave output pulses produced have a cycle time (T) equal to approximately 2 (0.693)*RC or 2lin (2)*RC. The output waveform frequency (ƒ) is therefore equal to: 0.722/RC. So for example, if we want to generate a 1kHz output square-wave waveform, then R = 3.3kΩ and C = 220nF using preferred component values.
