A system is needed to measure flow, which continuously cycles between 20 and 30 gal/min with a period of 30 sec. The required output is a voltage varying from -2.5 to +2.5 V for the cycling flow range. The sensor to be used has a transfer function..
Draw up a flow chart for testing any four-terminal MOSFET with an ohmmeter which can be used to conclusively determine which lead is the gate, which lead is the body, whether the device is an n-channel or p-channel, and whether the device is a D-m..
1. Calculate the length of time it takes for a signal to pass down an Ethernet bus that is 300 m in length, assuming the velocity factor of the cable is 0.66. 2. For the Ethernet bus in problem 1 and a communication rate of 10 Mb/s
This solution shows how to work from a given circuit implementation (a J-K flip flop circuit design) to derive the Boolean Logic and in so doing so simplify such logic using Boolean Algebra rules
The power transferred across the air gap of a two-pole induction motor is 24kW. If the electromagnetic power developed is 22kW, find the slip. Calculate the output torque, if the rotational loss at this slip is 400W
