Data Transmission Media

The data is transmitted from one place to other through different mediums. All transmission system has two devices i.e. transmitting and receiving end devices. These two devices are connected through a medium. there are two types of transmission i.e. Baseband transmission Broadband transmission Baseband transmission When data are sent without…


Sample and Hold Circuit Working

In this article, we will learn about Sample and Hold (S/H) Circuit. These circuits are used in Analog to Digital (ADC) conversion and Switched¬†Capacitor filters. Sample and hold circuits are used to sample an analog signal and to store its value for some length of time (for digital code conversion).…


Digital to Analog Converters (DAC)

A DAC (Digital-to-Analog Converter) is used to convert a digital signal to the analog format. An example of DAC: music stored in a DVD in digital format must be converted to an analog voltage for playing out on a speaker. Consider a DAC system having N-bit digital input and an…


Digital and Analog Quantities

When you read about circuits, you must come across terms analog and digital. Generally, electronic circuits can be analog circuits or digital circuits.¬†Digital electronics involves quantities with discrete values, & analog electronics involves quantities with continuous values. Let see the definition of the terms analog and digital. Analog quantity The…


Difference Between Asynchronous and Synchronous Counter

  S.No. Asynchronous Counter Synchronous Counter 1. All flip-flops are not clocked simultaneously. All flip-flops are clocked simultaneously. 2. Output of first flip-flop drives the clock of the second flip-flop, the output of second drives the third and so on. there is no interconnection between an output of one flip-flop…
