Design a sequential circuit that has one input X and one output Y. When X=1, the circuit repeatedly goes through sequences: 00, 01, 10, 11 and back to 00 …… When X=0, the circuit stays in whatever states it currently is. Y is set to one only when transitioning from 10 state to 11 otherwise it is set to zero. (a) Design this circuit using D-type Flip-Flops (b) Repeat your design and this time use J-K-Flip Flops

Asimple speed reducer is composed of 2 spur gears. the pinion gear has a pitch diameter of 0.75" and 36 teeth while the driven gear has a pitch diameter of 4.0" and 192 teeth. a)-what is the diametral pitch of each gear? b)-if an electric motor rotating ccw at 3000 rpm is coupled to the pinion, what is the rotational speed of the driven gear? c)-if the torque delivered to the pinion is 1 n-m, what is the torque on the driven gear? d)-what is the power transmitted by the gear train?
