Delayed Automatic Gain Control: Delayed Automatic Gain Control: Simple AGC is clearly an improvement on no AGC at all, in that the gain of the receiver is reduced for strong…
Frequency Changing and Tracking in Receivers: The mixer is a nonlinear device having two sets of input terminals and one set of output terminals. The signal from the antenna or…
Generation of Amplitude Modulation: There are two types of devices in which it may be necessary to the Generation of Amplitude Modulation. The first of these, the AM transmitter, generates…
Three Phase AC Voltage Controller: To control the current and voltage of three phase loads, Three Phase AC Voltage Controller are required. The single phase controller described previously can be…
Two pulse half controlled bridge converter: A Two pulse half controlled bridge converter is obtained by connecting a two pulse controlled midpoint converter in series with an uncontrolled one, as…
Characteristics of Protective Relay: Characteristics of Protective Relay elements using different operating principles. These principles and design criteria determine how well the basic function is performed and how in practice…
Pulse Width Modulation(PWM): Pulse width modulation of PTM is also often called Pulse Duration Modulation (PDM). In this system, shown in Fig. 18.8, we have a fixed amplitude and starting…
