You can generate a variable dc reference voltage with a DAC or with a PWM (pulse-width-modulation) signal from your controller (Figure 1). The accuracy of the voltage source that the ...

Sometimes you need to generate a pulse-width-modulation (PWM) signal for your circuit to simulate a certain behavior. The technique described here generates a simple programmable PWM signal for less ...

GENERATE_PWM_FROM_SAME_MCU 1 = Same micro-controller is used to generate PWM signal from Timer 0 or Timer 2 channels, as well as to measure and display this PWM signal using Timer 1 and Graphical LCD; ...

Abstract: A novel pulse width modulation (PWM) signal generation technique is proposed. The generator converts a single-bit digital signal into a PWM signal without a ramping waveform generator. The ...

Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required ...

How to use unfiltered PWM to drive high power loads. How to properly set the PWM duty cycle for high power loads. How to drive an incandescent lamp using PWM. Sometimes it’s necessary to drive a ...

This project explores a biomimetic approach to signal smoothing using an FPGA to implement PWM signal generation and IIR filtering. The design is inspired by natural systems' ability to filter and ...

Abstract: This paper new two simple PWM (pulse width modulation) signal generations based on a modified relaxation oscillator are introduced. The advantages of the proposed principle are that the ...
