Analog and Digital Converters - Technical MCQs

Q1:

In a flash analog-to-digital converter, the output of each comparator is connected to an input of a:

A decoder

B priority encoder

C multiplexer

D demultiplexer

ANS:B - priority encoder

It is formed of a series of comparators, each one comparing the input signal to a unique reference voltage. The comparator outputs connect to the inputs of a priority encoder circuit, which then produces a binary output.
