Design a counter which counts in the sequence: (20 points) 0000, 1001, 1000, 0111, 0110, 0101, 0100, 0011, 0010, 0001, 0000, a. Use D flip-flops.
b. Use J-K flip-flops.
c. Use S-R flip-flops.
d. Use T flip-flops.
e. Draw a complete state diagram for the counter of (b) showing what happens when the counter is started in each of the unused states.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
