Design a 3- bit Multipurpose Register. The register utilizes 3 "D" type flip flops with outputs Q0, Q1, Q2. The Registers has a synchronous clock input(CLK) that clocks all 3 flip flops on its positive edge The Registers has an asynchronous clear input(CLR' ) that sets all flip flops to "0" when active low. The Register has 2 select inputs, S0 and S1 that selects the functions as folows: S1 = 0, 0, 1, 1 and S0 = 0,1,0,1 and...
6. Design a 2-bit binary counter that counts, 0, 1, 2, 3, 0,. Use the 74LS374 IC, which has eight D flip-flops on it. They are positive-edge triggered, but it will not matter at all here You may draw a state diagram and then fill in the table Present State Q(t) Next State (D(t) - Q(t+1)) Q1(t) Qo(t) 7. Design a BCD binary counter that counts from 0 to 9 then back to 0 and repeat, displaying the count on...
Design a two-bit up/down binary counter using D flip-flops that can count in binary from 0 to 7. When the control input x is 0, the circuit counts down, and when it is 1, the circuit counts up. (a) Obtain the state table of the two-bit counter. (b) Obtain the state diagram (c) Draw the logic diagram of the circuit.
(a) Design an asynchronous Binary Coded Decimal (BCD) count-up counter using JK flip-flops. Draw the counter circuit clearly showing the configuration of the JK flip-flops and the necessary logic gate(s). Sketch the input and output waveforms of this counter (7 Marks) (b) The binary up/down counter for a cargo lift controller in a 7-storey building has an up-down (UID) control input and a buzzer output (B). The buzzer will sound B 1) when the lift is at level 1 or...

Design a 4-bit serial bit sequence detector. The input to your state detector is called DIN and the output is called FOUND. Your detector will assert FOUND anytime there is a 4-bit sequence of "0101". For all other input sequuences the output is not asserted. (a) (b) Provide the state diagram for this FSM. Encode your states using binary encoding. How many D-Flip-Flops does it take to implement the state memory for this FSM? (c) Provide the state transition table...

Using D-flip-flops, generate an 8-bit LFSR (Linear Feedbaclk Shift-Register). For every bit, include a Binary Control (BC) value that can turn the contribution of the flip-flop output to the XOR input on or off (1 for ON, 0 for OFF). For the 8-bit LFSR include a 7-bit ge- neric BIT_VECTOR that can configure contribution of LFSR flip-flops to the LFSR feedback. The right-most flip-flop output has no XOR, and the left-most flip-flop input is fed by the feedback line...
3. Design a counter with the following repeated binary sequence: 0,1,2,4,6. Use D flip-flop. 4. Design a counter to count with T flip-flops that goes through the following binary repeated sequence: 0,1,3,7,6,4. Find out the counter response towards the unused state. Illustrate the response with a state diagram. 5. Design a mod-7 counter (repeat binary sequence: 0,1,2,3,4,5,6) use JK flip-flop.
