Create a 4-1 mux using only tri-state buffers and inverters in logic works. this circuit will select one output from four inputs based on two addition switches. read textbook page 140 section 3-7 multiplexers before implementing this lab assignment (you can find the digital version of this section on the blackboard). you can test out your circuit using binary switches and a hex keyboard (use ctrl-f to show signal values).

a. this mux should have two selector lines so and s1 and four input lines a-d.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
