Continuous Balance DVM: Continuous Balance DVM - The basic block diagram of a servo balancing potentiometer type DVM is shown in Fig. 5.15. The input voltage is applied to one…

Successive Approximation Type DVM: The Successive Approximation Type DVM principle can be easily understood using a simple example; the determination of the weight of an object. By using a balance…

Principles of ADC (Analog to Digital Conversion): Principles of ADC - The input signal is compared with an internally generated voltage which is increased in steps starting from zero. The…

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…

Dual Slope Integrating Type DVM (Voltage to Time Conversion): Dual Slope Integrating Type DVM - In ramp techniques, superimposed noise can cause large errors. In the dual ramp technique, noise…

Ramp Technique of Digital Voltmeter: Ramp Technique - The operating principle is to measure the time that a linear ramp takes to change the input level to the ground level,…
