Difference between miller sweep circuits and bootstrap sweep circuit
Miller sweep circuit Bootstrap sweep circuit circuit diagram : Miller sweep circuit circuit diagram : Bootstrap sweep circuit In miller sweep circuit the polarity of sweep voltage is negative. In bootstrap sweep circuit the polarity of sweep
What is the need and types of multiplexing?
Multiplexing in the process of simultaneously transmitting two or more individual signals over a signals communication. Need multiplexing Multiplexing is the set of techniques that allows the simultaneous transmission of multiple signals across a signals data link.
How bootstrap sweep circuit is work?
The circuit diagram of bootstrap sweep is shown in above figure. In the bootstrap sweep circuits the transistor Q1 acts as a switch and Q2 as an emitter follower or a unity gain amplifier. The capacitor C1
Difference between analog communication and digital communication
Following are the difference between analog communication and digital communication: Analog communication Digital communication Analog communication is converted original information into equivalent analog signal. Digital communication is converted original information into equivalent digital signal. In analog communication the
What is meant by DSP (digital signal processor)?
The DSP stands for digital signal processor. The digital signal processor is a microprocessor exclusively designs to handle digital signal processing tasks. Digital signal processing algorithms typically require a large number of mathematical operations to be performed
What is mean by PSK ( phase shift keying)?
The PSK stand for phase-shift keying is the most efficient of three modulation technique. It is used for high bit rates. In PSK, phase of the sinusoidal carrier is changed according to the data bit to be transmitted. The simplest
