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

Digital and Analog Comparison Team C January 30‚ 2012 University of Phoenix NTC 362 Mathew Mower Technology is constantly changing in communications. The analog signal was used for several years and was limited in number and did not have the ability to handle the amount of data interchange used today‚ because of the size requirements. Analog signals are still used today‚ but are more complex and are in most circumstances converted to a digital signal. This paper will compare the different

Chapter 7 Digital Prepress Workflow Computer Basics The digital process was ushered in with the development of the computer. In the digital process‚ the computer processes information as binary digits or bits of information. A computer has electronic circuits which can be turned on and off at a rapid pace. A circuit that is turned on represents a value of one‚ and a circuit that is turned off represents a value of zero. A computer thus uses the binary system. People interpret and see

analog quantities must be converted into binary strings‚ representative of their values. The process of conversion of analog signals into their equivalent digital form is termed analog-to-digital conversion. The reverse form of the process is digital-to-analog conversion. Often‚ computers utilize these important processes for control of analog devices. To that end‚ for analog-to-digital (A/D) and digital-to-analog (D/A) converters to be useful‚ there has to be a meaningful representation of the analog

Human communication processes can be very intricate and complex. Considering that there are hundreds of ways for humans to send a message and just as many ways to receive or interpret a message‚ it is important to take the time and consideration to be a proactive communicator. Proactive communicators participate in the communication event‚ asking questions‚ following up and doing everything possible to make sure that the intended meaning is properly interpreted. It is also important to understand
