Transmission of Waves at Transition Points: Whenever there is an abrupt change in the parameters of a transmission line, such as an open circuit or a termination, the travelling wave undergoes a transition, part of…
Single Sideband Modulation (SSB): Single Sideband Modulation (SSB) can he obtained by passing the output of a carrier suppressor (product modulator) through filter circuits that are selective to transmit one sideband while suppressing the other.…
Monostable Multivibrator Using IC 555: The IC 555 timer can be operated as a Monostable Multivibrator Using IC 555 by connecting an external resistor and a capacitor as shown in the Fig. 2.102. The circuit…
Nodal Analysis Examples: Nodal Analysis Examples - we discussed simple circuits containing only two nodes, including the reference node. In general, in a N node circuit, one of the nodes is chosen as reference or…
Oxide Film Lightning Arrester: Oxide film lightning arrester operates on the fact that certain dry chemicals have the property to change rapidly from a good conductor to almost perfect insulator when slightly heated. For example,…
Effect of Negative Feedback on Bandwidth: The effect of negative feedback on bandwidth is given below as From Eq. (19.8) voltage gain with feedback is given as and from the above result it may be…
Requirements of Satisfactory Electric Supply Connection: The Electric Supply Connection in India is 3-phase a.c. operating at a frequency of 50 Hz. The power station delivers power to consumers through its transmission and distribution systems.…
Tripping of Impulse Generator: In large impulse generator, the spark gaps are generally sphere gaps or gaps formed by hemispherical electrodes. The gaps are arranged such that sparking of one gap results in automatic sparking…
Differentiator using Op Amp: A Differentiator using Op Amp circuit that performs the mathematical operation of differÂentiation. It produces an output voltage proportional to slope of the input voltÂage. A common application of a differentiator…
Voltage Level Translator (Level Shifter): Voltage Level Translator (Level Shifter) is usually an emitter follower circuit which is used to shift the dc level at the output of the intermediate stage downward to zero volt…
