Stroboscope Working Principle: The stroboscope working principle uses a high intensity light which flashes at precise intervals. This light may be directed upon a rotating or vibrating object. The stroboscopic…
What is Sampling Oscilloscope?: An ordinary Sampling Oscilloscope has a B.W. of 10 MHz. The HF performance can be improved by means of sampling the input waveform and reconstructing its…
Dual Trace Oscilloscope: Figure 7.19 (a) shows a block diagram of Dual Trace Oscilloscope. This CRO has a single electron gun whose electron beam is split into two by an…
Horizontal Deflection System in CRO: The Horizontal Deflection System in CRO consist of a Time Base Generator and an output amplifier. Sweep or Time Base Generator: A continuous sweep CRO…
Decade Counter Circuit: A Decade Counter Circuit is of flip-flops (F/Fs) in cascade, which counts in the base 10 (decimal number system). This means that there is a sequence of…
Digital Frequency Meter: Principle of Operation of Digital Frequency Meter - The signal waveform is converted to trigger pulses and applied continuously to an AND gate, as shown in Fig.…
Integrating Type DVM (Voltage to Frequency Conversion): The principle of operation of an Integrating Type DVM is illustrated in Fig. 5.5. A constant input voltage is integrated and the slope…
Principle Operation of Switching Power Converters: Controllable reactive power can be generated by dc to ac switching converters which are switched in synchronism with the line voltage with which the…
