Purpose: Gain experience converting from finite automata to regular expressions. Give regular expressions generating the following languages over {0,1}. Do these by hand by converting the finite automata. In your answers, you may use the shorthand Σ = (0+1) a. {w | w does not contain the substring 110} b. {w | w is any string except 11 and 111}
Finite Automata and regular Expression Given the following Finite automata: 1. 0, 1 0, 1 0, 1 What regular expression does it accept?

Find regular expressions for the languages accepted by the following automata.
Design a modulo-11 up/down counter using a regular modulo-16
counter and any combinational logic. The modulo-11 up/down counter
has four modes; count up by 1, count up by 2, count down by 1, and
no count. A formal description of the modulo-11 up/down counter is
shown below.
Inputs: ctrL0, ctrl-1 є {0, 1} State/Output:s (0,1, 10) The state transition function is defined as: s(t) if ctrl-0-0 and ctrl-1 = 0 (s(t)+ 1) mod 11 ifctl_0-0 and ctrl 1-1 s(t+1(s(t)+2) mod1...
