XOR

What is the hexadecimal equivalent of the binary number 1111?

F

If x = 1 and y = 0, what is the output of the expression x AND NOT y?

tma 2 10/10

In an SR latch, what does it mean when both inputs S\' and R\' are de-asserted?

The latch remembers its previous state

How is a stable state maintained in a bistable element when Q is initially set to 0?

Q remains 0 because of the feedback loop

How does the D latch with enable create a feedback loop to maintain state?

By connecting Q back to D

Why is it important for memory elements in sequential circuits to have feedback loops?

To maintain their state based on past inputs

Which component is necessary to create a bistable element?

Two inverters in series

How does a sequential circuit differ from a combinational circuit?

Sequential circuits depend on past and current inputs; combinational circuits only depend on current inputs

What happens to the output of a D latch when the enable signal E is asserted (E=1)?

The output follows the input D

What is the role of the enable signal in an SR latch with enable?

To control when the inputs affect the state

What does the truth table of the D latch indicate about the relationship between Qnext and D?

Qnext always equals D

What is a primary characteristic of the D latch with enable when E = 0?

It remembers its current state



TMA 3 7/10

In a BCD up counter, what happens after the count 1001 (9)?

It resets to 0000 (0)

In a BCD up-down counter, what happens when the count reaches 9 while counting up?

It reverses direction

In a 3-bit binary ripple up-counter, which flip-flop changes state most frequently?

The least significant bit (LSB) flip-flop

What causes the accumulation of delay in asynchronous counters?

The cascading of flip-flop propagation delays

How many flip-flops are required to create a counter that can count from 0 to 255?

9

What is the total delay in a synchronous counter?

Clock period

How can the MOD number of a counter be changed to a value less than 2^N?

By allowing the counter to skip states

In a digital clock application, what is the purpose of the MOD-50 counter?

To divide 50 pps down to 1 pps

What is the purpose of using a NAND gate in a MOD-6 counter design?

To clear all flip-flops when the count reaches 6

Good News for All Students!

The management has temporarily removed the Multi-Factor Authentication (MFA) requirement for attempting TMAs.

Possible Reasons:

*Email Delivery Issues: Many students had trouble receiving the MFA code in their student email, and some didn't get it in their alternative email either.

* Trap. Warning Against Third-Party Help: Be cautious of others offering to help with your login, especially if they’re using software or app that could compromise your results and semester. Always prioritize security and avoid giving out your login details to those you don't trust.

Make Use of This Opportunity Before MFA is Reintroduce!

Stay safe and take advantage of this temporary access!

Best Regards,

REGISTRATION UPDATE

Registration Closing On 15th of November: Ultimum of 11 days.

Do The Needful At Appropriate Time.There might be no extension again.

Exam registration closes:
