A ring conductor of radius 1 m is located on the xy-plane, centered at (0, 0, 0), and carries a current of 1 A in the counter-clockwise direction. A line conductor parallel to the y-axis and passing
A magnetic dipole mux of infinitesimal radius is located at (1, 0, 0). The magnitude of B at the origin (0, 0, 0) is 2.5 T. Find B in vector form at (3, 0, 0).
Two line conductors carry currents of 1 A and 2 A respectively. The first conductor is on the x-axis, while the other is parallel to the y-axis, and passes through the point (0, 0, 1 m). Find all po
Two very thin concentric rings lies in the xy-plane with their centers at the origin. The outer ring has a current of 1.5 A in the +uφ direction and has a radius of 50 cms. The inner ring has a
Consider a CMOS inverter fabricated in a 0.25-μm CMOS process for which VDD = 2.5 V, Vtn-Vtp = 0.5 V, and μnCox = 3.5μpCox = 115 μA/V2. In addition, QN and QP have L = 0.25 μm, and (W
If an FSM has N states, what is the maximum number of possible transitions that could exist in the FSM. Assume that no pair of states has more than one transition in the same direction and that no s
Draw a state diagram for an FSM (Moore machine) with no inputs and three outputs x, y, and z, where xyz should always exhibit the following sequence: 000, 001, 010, 100, repeat. Make 000 as the init
Draw a state diagram for an FSM that has an input X and an output Y. Whenever X changes from 0 to 1, Y should become 1 for two clock cycles and then return to 0, even if X is still 1. Develop both t
A point charge of 1.8mC is at the centre of a cubical Gaussain surface having each side 50cm. What is the net electric flux through the surface
The current in a solenoid is 5amps when it is connected to a 24v battery and 1.2amps when it is connected to a 24v, 60 Hz alternating current power source. Find the resistance and the inductance of
A 200 hp, 230 V, 500 rpm separately excited dc motor is controlled by a chopper. The chopper is connected to a bridge-diode rectifier supplied from a 230 V, 3 phase, 60 Hz ac main. The motor chopper
The motor details are as follows: 1 hp, 10V, 2500 rpm, 78.5 % efficiency, Ra=.01 O, La=.002 H, Kb= .03819 V/rad/sec. The chopper is one quadrant, and the on-state voltage drop across the device is a

A speech signal with bandwidth B= 10 Khz is sampled at F2 = 20 KHz. Suppose that the signal is corrupted by four sinusoids with frequencies. F1 = 10,000 Hz ,F2 = 8889 Hz, F3 = 7778 Hz , F4 = 6667 Hz
Design a low pass filter of gain 40 dB and corner frequency is 60 Hz assuming signal has a source of resistance = 100 ohms ( YOU want error propagation in pass band to be < 5% .
The display needs to tell you what direction you are about to move. The problem is WBNEC insists that you use a standard 7-Segment display. (Hint: You can tilt the display.) Design a decoder that wi
A 5000-Ω resistor and a 50-μF capacitor are connected in a series at t = 0 with a 6-V battery. The capacitor is initially charged. what is the current in the circuit at t= 0, and at t= 5, a
If I put a short in across the terminals a and b, does that mean the Isc = 0 since the capacitor would eventually charge and thus become an open circuit If so, how to do you find Vt and Rt
