Collector Modulation Circuit - Working, Advantages and Disadvantages: This is very popular method for AM generation. The circuit diagram for collector modulation is shown in Fig. 22.26. Here, the transistor Q1 makes an RF class…
What is System Management Mode (SMM) of the Pentium Processor? In system management mode, the high power is used up by the Pentium processors. In this mode, the Pentium processors use SMI# (input) and SMIACT#…
Types of Static Error: The static error of a measuring instrument is the numerical difference between the true value of a quantity and its value as obtained by measurement, i.e. repeated measurement of the same…
LM335 IC Temperature Sensor: LM335 IC Temperature Sensor - IC sensor produces a voltage or current signal that increases with increase in temperature. It eliminate the linearity errors associated with thermistor. However, being semiconductor devices,…
Steam Power Plants Interview Questions and Answers: 1. Why overall efficiency of a thermal power plant is very low ? Ans. In a steam power station, more than 50% of total heat of combustion is…
Speed Control of AC Commutator Motors: Speed control of ac commutator motors can be had either by varying the applied voltage or by movement of the brushes round the commutator. The former method makes use…
Circular Waveguide: It should be noted from the outset that in general terms the behavior of waves in circular waveguide is the same as in rectangular guides. Analysis of behavior: The laws governing the propagation…
Varistors or Voltage Dependent Resistors (VDRS): Varistors, also called the voltage dependent resistors (VDRs), show a high degree of nonlinearity between their resistance value and the applied voltage. They are made of non-homogeneous materials giving…
Bandwidth of RLC Circuit: The bandwidth of any system is the range of frequencies for which the current or output voltage is equal to 70.7% of its value at the resonant frequency, and it is…
Short Pitch Coil or Chorded Coil: Short Pitch Coil - So far it was assumed that the stator coils are full-pitched (a span of Ï€ rad elect). Coils may have a span of less than…
