A Digital Volt Meter (DVM) uses 10 MHz clock and has a voltage controlled generator which provides a width of 5µ sec/volt of unit signal. A 10 V input signal would correspond to a pulse count of
- A. 500
- B. 250
- C. 750
- D. 1000
Answer: A. 500
Explanation: Pulse count = Gate width × Clock frequency = (5 µs/V × 10 V) × 10 MHz = 50 µs × 10 pulses/µs = 500 counts.
