Q1:

A 6 bit dual slope A/D converter uses a reference of -6v and a 1 MHz clock. It uses a fixed count of 40 (101000). Then, what will be input, if the output register shows 100111 at the end of conversion.

A 5.85 V

B 6 V

C 5 V

D 10 V

ANS:A - 5.85 V

I/P voltage and reference voltage arc of opposite polarity.
