by Tarun Agarwal 6 years 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...
by Tarun Agarwal 6 years ago Frequency Shift Keying (FSK) Working & Applications The frequency shift keying is the most important digital modulation technique, and it is also known as FSK. A signal has the amplitude, frequency, and phase as properties. Every signal has these three properties. To increase any one of...
by Tarun Agarwal 6 years ago Amplitude Shift Keying (ASK) Working and Applications The most important and interesting concept in communication is Modulation. It has different types. Modulation is defined as the improving the signal characteristics amplitude, frequency or phase with reference of the carrier signal. If...
by Tarun Agarwal 6 years ago Phase Shift Keying (PSK) : Types and Its Applications The term PSK or Phase shift keying is broadly used in a radio communication system. This kind of technique is mostly compatible with data communications. It allows information in a more efficient way to be carried over a radio communications...
by Tarun Agarwal 6 years ago Frequency Modulation and Its Applications The FM or Frequency modulation has been available approximately since AM (Amplitude Modulation) although it has only some issues. FM itself didn’t have a problem apart from we couldn’t recognize the FM transmitter potential. In the...
by Tarun Agarwal 7 years ago Pulse Amplitude Modulation Today communication is the heart of technology. Communication is achieved over a transmitter and a receiver through signals. These signals carry the information through modulation. Pulse Amplitude Modulation is one of the kinds of modulation...
by Tarun Agarwal 8 years ago Difference Between PAM, PWM and PPM In a communication system, the modulation is an important step. Modulation is the process of transmitting a message signal (Baseband signal with low frequency) from transmitter to receiver without changing its characteristics (like amplitude,...
by Tarun Agarwal 8 years ago Differential Pulse Code Modulation Working and Application Differential pulse code modulation is a technique of analog to digital signal conversion. This technique samples the analog signal and then quantizes the difference between the sampled value and its predicted value, then encodes the signal...
by Tarun Agarwal 9 years ago Pulse Code Modulation and Demodulation We know that modulation can be defined as the process of changing the carrier signal’s parameters by the instant values of the message signal. The transmission of message signal can be done mainly for communication & the high-frequency...
by Tarun Agarwal 11 years ago What is Modulation and Different Types As we are living in an era of communication wherein we can easily transfer any form of information (video, audio, and other data) in the form of electrical signals to any other device or destined area. Although it is common in our perceptual...
