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
