The advantage of using a dual slope ADC in a digital voltmeter is that

For an ADC, match the following : if
List 1
A. Flash converter
B. Dual slope converter
C. Successive approximation Converter

List 2
1. requires a conversion time of the order of a few seconds
2. requires a digital- to- analog converter
3. minimizes the effect of power supply interference.
4. requires a very complex hardware.
5. It is a tracking A/D converter.

A 12-bit ADC is operating with a 1$$\mu $$ sec clock period and the total conversion time is seen to be 14 $$\mu $$ sec. The ADC must br of the
