Analyze the impact of the following situations on the operation of a ramp type digital voltmeter. Necessary explanation to be given to justify the answer.
(i) The output connection of the ground comparator of a ramp (negative ramp) type digital volt meter (DVM) is broken. What can be the consequence in measuring a voltage using this DVM?
(i) The output connection from the pulse generator (Oscillator) of a ramp type digital volt meter (DVM) is broken. What do you expect when measuring a voltage using this DVM?
(ii) A negative slope ramp type digital volt meter (DVM is used to measure 15V DC. The starting voltage of the ramp is kept at 10V DC. What result do you expect when this DVM is used to measure 15V DC?
