What is successive approximation type DVM?
The successive approximation type DVM is special type of potentiometric DVM in which a digital divider is used in the place of linear divider. The servomotor replaced by electromagnetic logic. The comparator compares the output of digital to analog converter with unknown voltage.
Which compare the output in a successive approximation type DVM?
Which compares the output in a successive approximation type DVM? Explanation: A comparator is used to compare the output of the digital to analog converter in a successive approximation type DVM. As a result the comparator provides high or low signals.
Which type of DVM is V to F conversion DVM?
Integrating type digital voltmeter (DVM): This voltmeter employs an integration technique that uses a voltage to frequency conversion. The heart of this technique is the operational amplifier acting as an Integrator.
What is successive approximation type ADC?
A successive-approximation ADC is a type of analog-to-digital converter that converts a continuous analog waveform into a discrete digital representation using a binary search through all possible quantization levels before finally converging upon a digital output for each conversion.
What is meant by successive approximation?
a method of shaping operant behavior by reinforcing responses similar to the desired behavior. Initially, responses roughly approximating the desired behavior are reinforced. Later, only responses closely approximating the desired behavior are reinforced.
What is the role of sample and hold circuit in successive approximation DVM?
The sample and hold circuit in the input of the DVM is to prevent the conversion error. This is because of the fact that when voltages other than D.C. are measured, conversion results are inconsistent.
What is the effect of IC chip on DVM?
Explanation: Advancement in IC chips have ensured the reduction in the cost of the DVM’s. Size and power needs of DVM’s have been reduced by a huge margin.
What is the output voltage in a dual slope integrating type DVM?
3. What is the output voltage in a dual slope integrating type DVM? Explanation: In a dual slope integrating type DVM, the output voltage is given by the integral of the input voltage. t1 is the time for which the capacitor is charged.
What is continuous balance type DVM?
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 side of a mechanical chopper comparator, the other side being connected to the variable arm of a precision potentiometer.
What are the types of DVM?
Types of DVMs
- (i) Ramp type DVM.
- (ii) Integrating type DVM.
- (iii) Potentiometric type DVM.
- (iv) Successive approximation type DVM.
- (v) Continuous balance type DVM.
Where are the successive approximation type ADC is used?
One of the most common analog-to-digital converters used in applications requiring a sampling rate under 10 MSPS is the Successive Approximation Register ADC. This ADC is ideal for applications requiring a resolution between 8-16 bits.
What is successive approximation in ABA?
SUCCESSIVE APPROXIMATION : is any behavior similar to a target behavior; it is usually one of a series of behaviors differentially reinforced in a program of shaping toward the goal of producing the target behavior.
The successive approximation type DVM is special type of potentiometric DVM in which a digital divider is used in the place of linear divider. The servomotor replaced by electromagnetic logic.
What are the various types of DVMs in general use?
The various types of DVMs in general use are. (i) Ramp type DVM. (ii) Integrating type DVM. (iii) Potentiometric type DVM. (iv) Successive approximation type DVM. (v) Continuous balance type DVM. i. Ramp type Digital Voltmeter. The operating principle of a ramp type digital voltmeter is to measure the time that a linear ramp voltage takes
How does a potentiometric DVM work?
In potentiometric type DVMs, the balance is not obtained manually but is arrived at automatically. Thus, this DVM is in fact a self- balancing potentiometer. The potentiometric DVM is provided with a readout which displays the voltage being measured. The block diagram of basic circuit of a potentiometric DVM is shown.
What is a digital voltmeter of successive approximation?
The block diagram showing a digital voltmeter of successive approximation type is shown in Figure. It consists of input attenuator and amplifier. The output of the input amplifier is given to the sample and hold circuit. There is a reference supply source whose output is given to the D/A converter.
