The simplified block diagram of a 10-bit A/D converter of dual slope integrator type is shown in figure.
The 10-bit counter at the output is clocked by a 1 Mhz clock.
Assuming negligible timing overhead for the control logic, the maximum frequency of the analog signal that can be converted using this A/D converted is approximately.
A. 2 KHz.
B. 1 KHz.
C. 500 Hz.
D. 250 Hz.
