ECE 171 Introduction to Digital Circuits Assignment - Portland State University, USA
Q1. Design a 2-bit magnitude comparator as depicted below. Specifically, create a truth table and then obtain minimal Boolean equations in SOP form for each output of the comparator. You do not need to draw a schematic. Note that A[1] is the MSB of A[1:0].
Q2. Design an expandable 2-bit magnitude comparator which can be used as shown below. You do not need to draw a schematic. The equations do not need to be minimal but must be incorporate the equations you derived above. Note that A[3] is the MSB of A[3:0].
Q3. In the communications scheme below three data bits are transmitted along with a parity bit from the source to the destination. The data should have even parity. Design both the parity generator and parity checker functions. The parity checker should output a 1 if there is a parity error. Use the fewest gates possible. You may use inverters and 2-input AND, OR, XOR, XNOR gates.
Q4. Design a 16-to-1 mux using only 4-to-1 multiplexers.
Q5. Design a circuit to multiply two unsigned 2-bit numbers using only 2-input AND gates and single-bit half adders.
Q6. What function is performed by the following ALU circuit when {M,P} = {01}?
Q7. Analyze the following synchronous state machine to determine its functionality by obtaining the next-state equations, the PS/NS table, and the state diagram. Does the state machine have any illegal states? What is the name of the counting sequence?
Q8. Assuming all the flip flops in the circuit below are initialized to zeros, show the output sequence it generates.
