Please help ASAP Construct the following circuit in Multisim

Please help ASAP. Construct the following circuit in Multisim and answer the following questions. If Multisim access is not available, then a manual solution is fine. Thank you in advance.

a) Make a table listing each of the binary values indicated by the LEDs in the circuit, in order beginning with 0002. To the right of each one, write the decimal equivalent of each

of the binary values.

b) Test the R switch. What does it do?

X1 X2 X3 VCC 2.5 V 2.5 V 2.5V 5V VCC J1 0 U2 U1 U3 SET SRT SET Key c J2 CLK CLE RESET RESET T-FF T FF T_FF Key R

Solution

a)

Here \"key C\" is used as clock input

If \"key C\" is in original position, there wont be any output(0 0 0). If we flip the switch(KEY C) outputs will change in the following order. Here X1,X2,X3 are LED and X1 is most significant bit(MSB), X3 is least significant bit(LSB)

b) \"Key R\" is used to reset all the flipflops(no matter what states flip flops are in, all will be resetted to zero(0 0 0))

Key C	X1 X2 X3	output	Decimal Equivalent
1st flip	0 0 1	X3 will glow	1
2nd flip	0 1 0	X2 will glow	2
3rd flip	0 1 1	X2,X3 will glow	3
4th flip	1 0 0	X1 will glow	4
5th flip	1 0 1	X1,X3 will glow	5
6th flip	1 1 0	X1,X2 will glow	6
7th flip	1 1 1	X1,X2,X3 will glow	7
8th flip	0 0 0	NO LED will glow	0
