  1. Ron Mancini EDN Converting periodic waveforms to square waves is an integral part of extracting a clock signal from data, creating waveform generators, and making timing-pulse generators. Any square-wave-conversion circuit is more valuable when the ...

  2. Chuck Wojslaw EDN The potentiometer portion of a mixed-signal, digitally programmable potentiometer adds variability to an analog circuit, and its digital controls provide programmability. You can use a digital potentiometer in two ways in an ...
  3. John Ambrose EDN Tracking notch filters find use in harmonic-distortion analyzers; they also can remove heterodyne noise from ham-radio systems. A conventional tracking switched-capacitor notch filter relies on a bandpass filter, a ...
  4. James Zannis EDN Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply voltage, thus protecting it ...
  5. Part 1 Understanding Raspberry Pi Inputs Push Button Switch Input The connections on the Raspberry Pi can be converted into inputs under software control. The example here is about the simplest; a push button switch is wired up to the 40-pin ...
  6. element14 Introduction The Raspberry Pi is a computer, and from a connections point of view it doesn’t look much different to a normal desktop computer. It has USB ports for connecting a keyboard and mouse, and a video output port for ...
  7. Luca Bruno EDN You can use the circuit in Figure 1 to obtain a low regulated voltage, such as 5 V dc, from a higher voltage, rectified, sinusoidal voltage source without resorting to an electrically noisy dc/dc converter or wasting watts in a ...

  8. Ricardo Jiménez, Fernando D. Pacheco, and Blanca L. Rodríguez Electronic Design Measuring the low frequencies that are common in many real-world situations, such as biomedical or speedometer applications, is a challenge due to the ...

  9. Stefan Strozecki EDN Many applications require current sources rather than voltage sources. When you need a high-current source, using a linear regulator is inadvisable, because of the high power dissipation in the series resistor. To solve the ...

  10. Marián Štofka EDN Many applications require a sampling circuit whose output is inverted with regard to the respective sample of an input signal. A simple approach is a cascade of a common noninverting sample-and-hold amplifier and an ...
