A sequential circuit has one input X and four outputs Z₁ Z₂ Z3 Z4. Z1 Z2 Z3 Z4 represents the gray code encoded number equal to the number of pairs of adjacent 1's that have been received as inputs. Use the gray code that is on page 22 of the textbook. For example, if the circuit had received 7 pairs of 1's as inputs, Z₁ Z2 Z3 Z4 = 1011. In addition, the circuit resets when the circuit receives 5 pairs of 1's. Find a Moore state graph and table for the circuit.

What is the smallest number of states in a Moore machine for which a Mealy machine could have fewer states? a. Two, since there could be a one-state Mealy machine that might do the same thing. b. Three, since there could be a simple Moore machine that went to one of two different states and always returned to the original state after that. For such a simple machine, a two-state Mealy machine is possible. c. You need at least four states to exploit the advantages of a Mealy machine over a Moore machine.
4. A Moore model finite state machine that acts as a "1011" sequence detector is to be designed using behavioral VHDL. Your design should detect overlapping sequences. Assume the input is named A, the output is named Z and that an active low reset signal asynchronously resets the machine. The VHDL ENTITY is given. Write the corresponding VHDL ARCHITECTURE to implement the FSM. Implement positive edge triggered flip-flops. library ieee; use ieee.std_logic_1164.all; entity fsm is port (a: in std_logic; clk: in std logic; reset n: in std_logic; z: out std_logic); end fsm; a) Draw the Moore model state diagram for the FSM. b) Write the VHDL architecture construct to implement the FSM.

Consider the following specifications of an alarm system: Four sensors w, x, y, and z are used as inputs and the alarm's sound S is used as output. If sensors w and z together detect an event, the output S must go ON. If sensors w, x, and y together detect an event, the output S must go ON. Otherwise, the output S remains OFF. a) Build a truth table for this system. b) From the truth table, derive a Boolean expression in both canonical and standard SOP forms. c) Using Boolean Algebra, simplify your expression to the minimum number of literals. d) Using K-map, find the simplified expression that you found in c). e) Implement the simplified expression with gates.
