ECE 294 - Analog and Digital Lab: Counters Quiz

What is a counter in digital electronics?

• A circuit that amplifies signals

• A sequential logic circuit that goes through a sequence of states

• A device that converts analog signals to digital

• A device that stores data

What is the modulus of a counter?

• The number of flip-flops in the counter

• The speed of the counter

• The type of flip-flops used in the counter

• The number of different states a counter can have

What is an asynchronous counter also known as?

• Parallel counter

• Serial counter

• Ripple counter

• Binary counter

What is a key characteristic of synchronous counters?

• They have a cumulative flip-flop delay

• All flip-flops are clocked by the same clock signal

• They are slower than asynchronous counters

• They use D flip-flops

Which flip-flop is commonly used in synchronous counters?

• SR flip-flop

• J-K flip-flop

• D flip-flop

• T flip-flop

How can a count-up ripple counter be converted to a count-down ripple counter?

• By using a different type of flip-flop

• By changing the modulus of the counter

• By adding more flip-flops

• By changing the clock input to the flip-flops

What is the role of the J and K inputs in a J-K flip-flop?

• To reset the flip-flop

• To control when the flip-flop changes state

• To provide power to the flip-flop

• To store data

What is the main disadvantage of ripple counters?

• They are complex to design

• They are expensive

• They are relatively slow due to propagation delay

• They require a large number of flip-flops

What is the purpose of the prelab assignment in the experiment?

• To design a new counter

• To build a prototype of the counter

• To estimate the highest possible clock frequency for the counters

• To write a report on counters

What is the main feature of a synchronous counter?

• It uses fewer flip-flops

• It has a higher modulus

• It synchronizes data transfer with a master clock signal

• It is cheaper to build
