Question

A Digital voltmeter uses a 10 MHz clock and has a voltage controlled generator which provides a width of $10\mu s/volt.$ A 10 V input signal will correspond to pulse count of ______

• A. 1000
• B. 100
• C. 10
• D. 10000

Answer 1

The correct option is A 1000

$Timeforonecount=\frac{1}{10\times {10}^6}={10}^{-7}\sec$

$TotalTime=10\times 10\times {10}^{-6}=100\times {10}^{-6}\sec$

$Count=\frac{100\times {10}^{-6}}{{10}^{-7}}=1000$
