2.5 A digital voltmeter uses a dual slope A/D converter. The reference voltage is 1 V, the clock frequency is 1 kHz and the counter is a 3-decade counter. If the integrating capacitor charges to 5 V in 1 s and discharges at the rate of 10 V/s, what is the input voltage if the counter has stored 1500 pulses?
