In this Design Idea, the total time period of an output pulse’s width is 16 times the pulse width of the input clock. The input clock connects to a binary counter (Figure 1). The output of the binary ...

Pulse Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This method ...

Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

Feel like breaking out of your streaming-induced vegetative state but can’t seem to break the binge-watching cycle? Maybe you’re a candidate for this exercise bike that controls how much Netflix you ...

Use the FPGA as a CPU which allows you to add predefined I/O blocks Build custom peripherals for an external CPU from predefined I/O blocks Build custom logic circuitry from scratch Projects that ...

Simply adding a diode and potentiometer to a 555 timer operating in the asynchronous mode yields a pulsewidth modulator (PWM) with a duty factor adjustable from 1% to 99% (Fig. 1). Applications would ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

I’ve spent a lot of my career building analog-to-digital converters (ADCs) from whatever bits of stuff I can find lying around. In many cases, someone has decided that an analog signal needs to be ...
