True or False.
10. The flip-flop is a sequential logic circuit.
11. A multiplexer is a digital switch connecting data from one of n sources to its output.
12. Digital circuits produce exactly the same results for given set of inputs.
13. A Karnuagh map is a graphical representation of a logic's function truth table.
14. The combinational circuit depends only on its current inputs and voltage parameters
Homework Answers
10. True. Flip-flops are an example of basic sequential circuits as it's outputs also depend upon the previous inputs.
11. False. A Multiplexer has Analogue counterparts as well made up of transistors.
12. False. It is true for combinational circuits but digital circuits include sequential circuits as well and they do depend on the previous outputs.
13. True. K-Maps or Karnuagh Maps represent the truth table of a logic and help minimize it.
14. True. Combinational circuits do not depend upon the previous sequence of inputs but only on the current input and the voltage parameters(clocks for example).

task 1: In digital electronics and modern computer hardware, a flip-flop is sequential digital circuit used as a basic memory element. It has two stable states and can be used to store state information. One of its states represents '1' while the other represents '0'. The most common types of flip-flops are SR-flip-flop, JK-flip-flop, and D flip-flop. When used in a finite-state machine, the output and next state depend not only on its current input, but also on its current...

1. (10) Which of the following describes the operation of a positive edge-triggered D flip-lop? A. If both inputs are HIGH, the output will toggle. B. The output will follow the input on the leading edge of the clock. C. when both inputs are LOW, an invalid state exists. D.

Why can't we design a combinational digital logic circuit to control a light so that the light changes state any time its "push-button" switch is pressed? (Press and release the button, and the light changes state. Press and release again, and the light changes state again.) Try to list as many properties this circuit needs to have that we cannot model as you can! Reminder: a "combinational digital logic circuit" takes one or more boolean inputs and feeds them through...
