1.	Controlled buffers can be useful ____________(a) To control the circuit’s output into the bus(b) In comparison of component’s output with its input(c) In increasing the output from its low input(d) All of the MentionedThe question was posed to me during an interview.My query is from 4-Bit Parallel Adder/Subtractor topic in division Arithmetic Circuits of Digital Circuits
Answer» Right choice is (a) To control the CIRCUIT’s output into the BUS Explanation: Controlled buffers can be useful when you have a wire (often called a bus) whose value should match the output of one of SEVERAL components. By placing a controlled buffer between each component output and the bus, you can control WHETHER that component’s output is fed ONTO the bus or not.
