Design a 4-bit circuit for 2s-complement, base on the formula below, using only inverters, 2 input AND gates and 2 input OR gates. Design your circuit to be as fast as possible. What is the worst-case propagation delay for this circuit, assuming a 1 ns delay for each inverter and a 2 ns delay for each AND gate and OR gate? (hint: for all i>0 use the formula below) , what about i=0? Note that x is input and x3 as the most significant bit and is y is the output, similarly y3 is the most significant bit.
For a circuit with resistor of 10 K ohm and a capacitor of 5 micro Farads, what is the time constant in second?
(b) This voltage is measured using a defective voltmeter, which always indicates a lower reading than the actual value. Suppose the voltmeter reading is 2.5*10^(-4). Calculate the probability that the error is not more than 0.5 *10^(-4).
With V=100V, the instantaneous power into a network N has a maximum value 1500 W and a minimum value ?247 W. (1) Find a possible series RL circuit equivalent to N. (2) Find S=P+jQ into N.
A plant has two identical standby generator units for emergency power use. In the area of the generators, the normal noise level registers 81 dBA on the sound-level meter with the generators turned off. When one generator switches on, the noise le..
If it takes 1 sec to rotate 45 degrees after starting from rest, how long in seconds would it take to instead rotate 81 degrees after starting from rest under the same constant angular acceleration.
A telephone switching board can handle 120 phones. Assuming the following, and determine the outgoing traffic intensity and the number of channels
What is the primary purpose of a resistor in series with a LED being driven by a flip-flop?
A circular loop TV antenna with 0.01 m2 area is in the presence of a uniform -amplitude 300 MHz signal. When oriented for maximum response, the loop develops an emf with a peak value of 20 mV. What is the peak magnitude of B of the incident wave?
