The measurement cycle begins with the spring in a relaxed state. The unknown voltage is applied to the input of the integrator, an output voltage(E o ) starts to rise. For a fixed time interval, the analogue input is applied to the integrator via switch S. The level of the input voltage is raised in the comparator to some desired positive value … Hence it is called a s dual slope A to D converter. When compared to other types of ADC techniques, the dual-slope method is slow but is quite adequate for a digital voltmeter used for laboratory measurements. A voltmeter with a sensitivity of 100 mV may have its bandwidth as 5 MHz only. Then the output signal of integrator experiences a negative slope, which is constant and proportional to the magnitude of the input voltage. When the gate opens, the output of the oscillator (clock pulses) are allowed to pass through it and are applied to the counter. The logic diagram for the same is shown below.
