The Digital-to-Analog Converter (DAC) and the Analog-to-Digital Converter (ADC) circuits are discussed here. A Digital to analog converter (DAC) converts binary digital data to an analog form by using an R-2R ladder (binary weighted resistor) network and a summing amplifier. It uses an op-amp (741) as a summing amplifier. You can learn how to build aDigital to Analog … [Read more...] about Basic DAC and ADC Circuits – How to Build

How to Connect an Oscilloscope to a Circuit
Oscilloscopes are an important tool in any electrical engineer's lab. A specific and exact guideline is maintained to connect an oscilloscope to a circuit. In particular, proper grounding is very vital for your safety as well as the safety of the integrated circuits (ICs) you're testing. Setting oscilloscope controls, calibrating the oscilloscope, connecting oscilloscope … [Read more...] about How to Connect an Oscilloscope to a Circuit
How to Find VPP on Oscilloscope
Adjust the vertical sensitivity of the oscilloscope while the waveform is displayed on the screen to get the figure as inclusive as possible without losing any from the top or bottom. Count the number of horizontal graticules on the screen from the bottom of the figure to the top of the figure. Multiply that amount by the sensitivity level that has been set. What Does VPP … [Read more...] about How to Find VPP on Oscilloscope
How to Measure Current With an Oscilloscope
You can measure current with an oscilloscope using one of the following methods: Measuring the voltage dropped across a shunt resistor.Measuring current with a current probe. Measuring current with a digital multimeter is common. But measuring current that changes over time necessitates the use of an oscilloscope. Most oscilloscopes only detect voltage directly, not … [Read more...] about How to Measure Current With an Oscilloscope
How to Zoom In Oscilloscope
To zoom in or out a signal in an oscilloscope, you need to change the scales of the axes. Use the knob for the horizontal axis and set the µs/div to a lower value. This will allow you to zoom on your signal horizontally. To zoom vertically, set the volts/div of your oscilloscope to a lower value. Zooming in on waveforms allows you to view a detail of the signal … [Read more...] about How to Zoom In Oscilloscope
