February 8‚ 2013 Math- POW POW: A Digital Proof Problem Statement: This problem of the week has a main gain goal set upon boxes. There are five boxes numbered one through zero. Underneath the boxes have the numbers written under them. In the boxes‚ there are numbers that should be entered in the boxes that all evenly works out. For instance‚ the number that you put in box zero must be the same as the number of zeros that were used. The same procedures apply when using

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

The digital revolution has changed people’s life deeply through the invention of the computer and the revolution of the communication technology. However‚ the revolution can also be regarded as the wicked problem from certain aspects. The digital revolution has mainly three properties of the wicked problem. The digital revolution has no stopping rule (Camillus 2008). Since the digital revolution represents the third industry revolution in the history‚ people are very dependent on the digital products

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
