S2 S1 S0 Operation 0 0 0 No change 0 0 1 Rotate left 0 1 0 Rotate right 0 1 1 Reset 1 0 0 Set 1 0 1 Count down 1 1 0 Count up 1 1 1 Load external bits I 2 I1 I0

Answer #1

Design a 6-bit, shift-right register with D flip flops, and use
it to implement a circuit that detects the sequence “010010” (the
rightmost bit is the first arriving). Information shifts one
position right when a positiv edge of clk occurs The circuit has
the following inputs and outputs (use exactly these names for
inputs and outputs. Respect upper and lower case):
clk: Input. Clock signal.
RST: Reset signal. When RST = 1 flip flops are reset to 0.
IN: Data...

We wish to design a digital system with two
flip-flops, say B and C, and one 10 bit binary Counter A, in which
the individual flip-flops are denoted by A10, A9, A8, A7, A6, A5,
A4, A3, A2, A1.
A start signal S initiates the system operation by clearing the
counter A and flip-flop C, and setting flip-flop B to one.
The counter is then incremented by one starting from the next
clock pulse and continues to increment until the...

What design is more effective a n 3 - Bit sequential counter
with T Flip-Flops or a 3 - Bit sequential counter with D
Flip-Flops. Why? Explain.

Ripple Counters and T-FFs.
(a) Design a 5-bit ripple down-counter using T Flip-Flops and no
other components.
(b) Design a 5-bit ripple up-counter using T Flip-Flops and no
other components.
(c) What limits the maximum counting speed of your ripple
counters?
(d) Design a T Flip-Flop using only a D flip-flop with no extra
logic gates.

4-bit register using jk flip flops.
1)What is the purpose of anding the clock signal and the load
input together in your circuit?
2) How would I be able to store 1011 into the 4-bit register?
Explain the process. For example, what do your inputs should be?
Should your clock be on or off? How about your load input? How does
your load input work when you want to store bits into your
register?
3) If your load input is...

Design a 4 bit counter of even numbers (0,2,4,6,8,10,12,14) using
jk flip flops that holds when input is 0 and moves to the next
state when input is 1

Design 3 - Bit sequential counter with T Flip-Flops. Provide the
below:
1. State Diagram:
2. State Table:
3. K-maps and equations:
4. Logic Diagram:

Using Quartus II and the DE2 board, design and demonstrate a
3-bit up-counter; use D flip flops for this project. Use one of the
debounce switches for a clock and 3 LEDs to indicate the count.
Implementing PRE and CLR will improve your design.
1. Please hand in a schematic and functional and timing
simulation of your circuit.

Design 3 - Bit sequential counter with D Flip-Flops. Provide the
below:
1. State Diagram:
2. State Table:
3. K-maps and equations:
4. Logic Diagram:

Design 2 bits counter that count down by using T flip flop when
input x =1 and counts up
when x=0. Find the following
1. Derive the state table
2. Derive the K‐map simplifications.
3. Draw the logic diagram
