Types of Protective Relays: Basically, Types of Protective Relays are analogue-binary signal converters with measuring functions. The variables such as current, voltage, phase angle or frequency and derived values obtained…
Bandwidth Requirement in Communication System: It is reasonable to expect that the frequency range i.e., Bandwidth Requirement in Communication System for a given transmission should depend on the Bandwidth occupied…
Pulse Code Modulation(PCM): Pulse Code Modulation(PCM) is different from the other forms of pulse modulation studied so far, PCM also uses sampling techniques, but it differs from the others in…
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…
Frequency Modulation Recording: When a more accurate response to dc voltages is required, an Frequency Modulation Recording system is generally used. In this FM system, the input signal is used…
Frequency Shift Keying Demodulator Working (FSK): In digital data communication, binary data is transmitted by means of a carrier frequency. It uses two different carrier frequencies for logic 1 and…
Important Questions of Integrated Circuits: Give classification of integrated circuits. Compare IC families on the basis of substrate used, structure, active devices, passive devices and applications. What are the different…
