3. The duty cycle of the square wave is 50%, which means the high and low time periods are equal.(方波的占空比为50%,意味着高电平和低电平的时间是相等的。) 4. The duty cycle of the switching power supply can beadjusted to regulate the output voltage.(开关电源的占空比可以被调节以调节输出...
In the case of a square wave the duty cycle is 0.5 (50%) since the pulses are present 1/2 the time, the definition of a square wave. For Figure 1, the pulse width is 1 unit of time and the period is 10 units. In this case the duty cycle is: PW/T = 1/10 = 0.1 (10%)...
Most square wave generators with duty cycle and frequency control do not provide the ability to adjust the parameters independently. The circuits described below solve this problem. Figure 1 shows a square wave oscillator built with standard CMOS Schmitt-Trigger inverters and NOR gates such as the ...

A method and apparatus for determining the phase angle between two periodic square wave signals is disclosed in which the two square wave signals are applied to respective inputs of an exclusive OR gate, the output signal of which is applied to a first input of a digital selection circuit. ...
duty cycle value. I was thinking of a Ramp or some sort of looping which I have tried but doesnt seem to work. My working code for the PWM with manual change of duty cycle is as follows: static void pwm_main(void) ...
I am wanting to create a square wave in MATLAB that increases it's duty cycle with respect to time, however when I tried to implement this, I ran into the error of MATLAB only allowing scalar values for the duty cycle. Is there any way around this?

A dimmer circuit for an HID lamp is provided for supplying a square wave current therethrough at a constant frequency, but whose duty cycle is variable dependent on a sensed current level. The circuit employs a first pair of transistor switches for reversing polarity through the lamp at a low...
writePWMDutyCycle(mypi,pinNumber,dutyCycle)writes the duty cycle of the output square wave to the output pin. The PWM uses a software implementation allowing all GPIO pins on the Raspberry Pi®hardware board to operate as a PWM pin. Each PWM pin outputs a square waveform with variable fr...
