Successive approximation Also known as shaping behavior, successive approximation modifies behavior by rewarding animals as they make attempts toward the desired behavior. The slope of output voltage is determined by the value of input voltage This voltage is fed a level detector, and when voltage reaches a certain reference level, the detector sends a pulse to the pulse generator gate. Thus, this DVM is in fact a self- balancing potentiometer. The increasing popularity of DVMs has brought forth a wide number of types employing different circuits.

In this category of DVM, the ADC employed makes use of successive approximation converter. Actually when we employ the voltage to frequency conversion techniques, a train of pulses, whose frequency depends upon the voltage being measured, is generated. Engineers, being clever, have reached the same conclusion and have designed hybrid ADCs that use flash converters for the most significant bits, then successive approximations (or sigma-delta) for less significant bits. The successive approximation ADC generates a series of digital codes each corresponding to a fixed analog level with an internal counter to compare with the analog signal under conversion.

The increasing popularity of DVMs has brought forth a wide number of types employing different circuits. These ADCs use a comparator to compare input voltage and the output of an internal digital-to-analog converter, successively judging whether the input is above or below a narrowing range’s midpoint. Successive Approximation DVM. If we repeat this process, a third approximation is obtained: \[ x_{3} \approx 0.0182 \] in exact agreement with the accurate result obtained from the quadratic formula in the example. D/A converter generates the set pattern successively. In 1999, Paul Chance defined shaping as “the use of successive approximations to achieve a target behavioral goal.” In 2017, David Pierce and Carl Cheney used an almost identical definition, adding only that shaping includes the use of “selective reinforcement.”Based on those definitions, most of us use shaping every time we train. Thus no more pulses from the clock oscillator can pass through to trigger the pulse generator. Due to this, MSB of the control register is set to high and all other bits to low. d) generate sequence code The successive approximation typeDVMis special type of potentiometric DVM in which a digital divider is used in the place of linear divider.

In fact, for the same accuracy, a digital voltmeter now is less costly than its analog counterpart. Successive-approximation-register (SAR) analog-to-digital converters (ADCs) are frequently the architecture of choice for medium-to-high-resolution applications with sample rates under 5 megasamples per second (Msps). The major draw of digital ramp ADC is the counter used to produce the digital output will be reset after every sampling interval. The output of SAR is given to n-bit DAC. Since one pulse from the pulse generator is produced for each cycle of the saw tooth wave, the number of pulses produced in a given time interval and hence the frequency of saw tooth wave is an indication of the voltage being measured. AB - During successive approximation analog to digital conversion a series of successive digital reference values is selected that converges towards a digital representation of an analog input signal. 2) Figure 1 shows the block diagram of successive approximation DAC. Successive approximation ADC is the advanced version of Digital ramp type ADC which is designed to reduce the conversion and to increase speed of operation. Numerical readout of DVMs is advantageous since it eliminates observational errors committed by operators. This ADC is ideal for applications requiring a resolution between 8-16 bits. It measures the input voltage after converting the analog voltage to digital voltage and displays it in number format using a convertor. In potentiometric type DVMs, the balance is not obtained manually but is arrived at automatically. Though there are many types of A/D converters, we will be discussing only about the successive approximation type. Since the frequency of these pulses is a function of unknown voltage, the number of pulses counted in that period of time is an indication of the input (unknown) voltage.
