by Tarun Agarwal 5 days ago Hexa to ASCII and ASCII to Hexa Conversion with Example Data in the form of text and numbers are used for programming the electronic devices. But computers cannot understand human language. They can only understand the data in the form of 0’s and 1’s. To make data interpretable by...
by Tarun Agarwal 6 days ago Decimal to Octal and Octal to Decimal Conversion with Example Numbers are the arithmetical symbols used to represent a particular quantity, for counting and making calculations. Over the world, different cultures have introduced and used different symbols for representing numbers. The Tally system...
by Tarun Agarwal 4 weeks ago Quadrature Amplitude Modulation In the amplitude modulation scheme, we can modulate one message signal (input signal) which is in analog form. It means we can give only one input signal and we can modulate it and transmit to the destination level. And the effective utilization...
by Tarun Agarwal 1 month ago Time Base Generator – Working Principle and Circuit Diagram For the testing or repairing of analog circuits, function generators, the electronic test equipment, are used as a signal source. For digital circuits, pulse generators are used. Function generators can produce both single-shot waveforms...
by Tarun Agarwal 1 month ago Quadrature Phase Shift Keying In a communication system, modulation is the method by which the properties of the carrier signal are varied according to the message signals. There are two types of modulation methods based on the type of baseband signal. They are Analog...
by Tarun Agarwal 1 month ago Binary Phase Shift Keying Communication is the process of transfer of information from one place to another. There are various means of communication being used today. The evolution in the field of communication took up pace during world war. From wired communication...
by Tarun Agarwal 2 months ago NFC Sensor Working and Its Applications The term NFC stands for “Near Field Communication”. At present it is growing very fast in various smartphones, however, it works internally within the mobile phone. But we don’t know about its working. Nowadays, it is mainly using...
by Tarun Agarwal 2 months ago Basics of Optical Transmitters and Receivers with Specifications At present, the growth in information technology has increased using the current telecommunication systems. Mostly, OFC (optical fiber communication) plays an essential role in the telecommunication system development with a high speed...
by Tarun Agarwal 2 months ago Adaptive Delta Modulation – Block Diagram and Applications In communication systems, the modulation methods are used to transmit signals over long distances. In the modulation process, the properties of a high-frequency signal such as amplitude, phase, etc… are changed according to the low-frequency...
by Tarun Agarwal 2 months ago Delta Modulation With It’s Block Diagram When signals are transmitted over long distances, they get affected by noise and interference. There are several methods invented for effective transmission of signals over long distances without any error. The conversion of analog signals...
