Construction Digital Voltmeter Raj K. Gorkhali A voltmeter finds its importance wherever voltage is to be measured. Here we present an easyto-build and accurate digital voltmeter that has been designed as a panel meter and can be used in DC power supplies panels or where it is necessary to have an accurate indication of the voltage. Circuit description The circuit uses an analogue-todigital converter ICL7107 made by INTERSIL. Fig. 1 shows the pin detail of IC L7107. This IC incorporates in

digital electronic is the branch in which most of the devices used work on direct current. this current is very less as compared to the current used in electrics. The direct current is more dangerous as compared to the altenating current‚ but it is harmful after a certain range like above 18 volts. But all the electronics appliances work below this range . The main things in digital electonics are 0 and 1.The whole of the digital electronics depends on 0 & 1. where o stands for ’off’ and 1 for

A digital storage oscilloscope is an oscilloscope which stores and analyses the signal digitally rather than using analogue techniques. It is now the most common type of oscilloscope in use because of the advanced trigger‚ storage‚ display and measurement features which they typically provide.[1] The input analogue signal is sampled and then converted into a digital record of the amplitude of the signal at each sample time. The sampling frequency should be the Nyquist rate or better to avoid aliasing
