Frequency Domain Network Function: As the frequency domain network function is a complex function, it can be expressed mathematically in two ways i.e. using rectangular coordinates or using polar coordinates. In rectangular coordinates it can…
Frequency Response of RC Coupled Amplifier: The curve drawn between the voltage gain and signal frequency of an amplifier is known as the frequency response. The performance of an frequency response of RC coupled amplifier…
Classification of Relays: The protective relay may be defined as an electrical device interposed between the main circuit and the circuit breaker in such a manner that any abnormality in the circuit acts on the…
Ward Leonard Method of Speed Control of DC Motor: Ward Leonard Method of Speed Control of DC Motor is combined armature and field control and is therefore, operationally the most efficient method of speed control…
Tropospheric Scatter Propagation: Tropospheric Scatter Propagation is a means of beyond-the-horizon propagation for UHF signals. Tropospheric Scatter Propagation uses certain properties of the troposphere, the nearest portion of the atmosphere (within about 15 km of…
Network Topology: Basically network analysis is nothing but finding unknown branch currents or voltages across various branches. We can find these unknown parameters by using different network simplification techniques. These network simplifications involves basic Kirchhoff's…
Bandpass Analysis: There exist many practical situations in which multiple filtering and band pass analysis are required. In multiple filtering, one specific operation (for example low pass, high pass, band pass, etc.) is required to…
Voltage Level Detectors: Voltage Level Detectors - Operational amplifiers are often used in circuits in which the output is switched between the positive and negative saturation voltages, +Vo(sat) and -+Vo(sat). The actual voltage change that occurs…
Quasi Complementary Push Pull Amplifier: In practical power amplifier circuits, it is preferable to employ NPN transistors for both high-current output devices. As the push-pull connection needs complementary devices, a PNP high power transistor is…
Three phase Fully Controlled Rectifier Control of DC Separately Excited Motor: Three phase Fully Controlled Rectifier Control (6 pulse) fed separately excited dc motor drive is shown in Fig. 5.32(a). Thyristors are fired in the…
