2. Design a two-bit up/down binary counter using T-fip-flops that can count in binary from 0 to 3. When the control input x is 0, the circuit counts up and when it is 1, the circuit counts down. (a) Obtain the state table of the two-bit counter (P. S., Input, N. S., Output). (b) Obtain the state diagram. (c) Draw the logic diagram of the circuit.

BIT MAXIMUM VALUE SELECTOR Consider a simple device that takes two 2-bit binary inputs representing two values ranging from zero to three. The 2-bit value A is represented by two input variables Al and A0. Values of Al and A0 will be used to encode numeric values (in binary) as described below. 2-bit values for the second 2-bit input B and the 2-bit output C are encoded similarly. The 2-bit output C of the de- vice will be the greater...

2. A 2xl mux has two single-bit inputs and one selector bit (S). Such a mux allows you to choose one of the single-bit inputs to appear at the output. Let's say, you want to use four 2x1 such multiplexers to construct a 4-bit 2X1 multiplexer with selector (S). Such a multiplexer can be used to choose among four 4-bit inputs (see figure below). If A, B are all 4-bit inputs and are connected to the inputs of the multiplexer....

Design a circuit to add two 2-bit binary numbers and display the results of the addition as a 3-bit binary number, with the most significant bit be the carry out. To do this, you will use the four switches on your Breadboard Companion as your two 2-bit number inputs. Three of your LEDs will be used to represent the 3-bit output of your circuit. Complete a truth table for the expected output values on the lab data sheet attached. Use...

1. Suppose you want to design a 2-bit binary up-counter. Construct the state table using A1 and AO as the previous state of bits and A1+, A0+ as the next bit states, ie, to count from 00 to 01, A1 stays at 0, but AO changes from 0 to 1. Let the counter wrap-around, such that 11 -> 00. Draw the state diagram. 2. Next, add in a third input, En, for enable. The counter can only count up when...
