Voltage and Current Divider Rule: Voltage and Current Divider Rule is explained by two conditions, namely Voltage Division in Series Circuit of Resistors Current Division in Parallel Circuit of Resistors…
Basic Components of Static Relays Articles Semiconductor Diodes in Static Relays: The pn junction has rectifying characteristics as shown in Fig. (10.1). If a source of emf is connected to…
Coincidence Type Phase Comparator: The basic concept of phase comparison is simpler in that it is possible to deal with signals of equal strength whose coincidence (or noncoinecidence) is readily…
Static Amplitude Comparator: If the two input signals are S1 and S2 the amplitude comparator gives positive (yes) output only if S2/S1 ≤ K (Fig. (11.1)), S1 is the operating quantity…
Square Wave Generators: Diode clippers can be used to remove the curved portion of the sinusoidal wave to give square waves. The operational amplifier together with an integrator, can be…
TV Video Waveform: Blanking - TV Video Waveform voltage is limited to certain amplitude limits. Thus, for example, the white level corresponds to 12.5 percent (±2.5 percent) modulation of the…
Measurement of High Voltage and Currents Articles: Series Resistance Microammeter: High d.c. voltages are usually measured by connecting a very high resistance (few hundreds of megaohms) in Series Resistance Microammeter…
Signal Conditioning in Instrumentation Articles: Signal Conditioning System: The measurand, which is basically a physical quantity, is detected by the first stage of the instrumentation or measurement system. The first…
