draw a possible three phase motor that is based on two rotating electric fields and explain 1) the basic principle; 2) the drawback of the electric field based machine when it is compared to magnetic field based machines
The counter will use the falling edge of the clock (denoted by Clk) and have a separte reset pin (R) which will reset the counnter to 0000 when it is low (e.g. R=0). Please use D type flip-flops. write down the state diagram , and state table.
1. Determine the minimum value of gain K when Gc(s)=K, so that the steady-state effect of a unit step disturbance Td(s)=1/s is less than or equal to 5% of the unit step (y(inf)=0.05). 2. Determine whether the system using the gain of part 1 is stab..
Design a non-inverting op-amp with a bandwidth of 20kHz whose open-loop gain is 100,000 and unity gain frequency of 1 MHz. Draw the Voltage Transfer Characteristic (VTC) of the designed op-amp if the power supply produces ±10V.
