If the overall impulse response of a data communication system is araised cosine pulse with 100% excess bandwidth (i.e. roll-offfactor of 1), then find the height and the width of the eye pattern.
An infinite sheet of surface current density given by (equation 1) A/m exists on a plane defined by x=1. A second infinite sheet of surface current density given by (equation 2) is on the plane defined by x = -2. What is the magnetic field intensi..
Operation of NPN Bipolar Transistor : a. Describe the operation of a typical NPN bipolar junction transistor used both as an amplifier and a switch. b. List the 4 regions of operation and draw I-V characteristic curve.
build a cicuit that must be able to operate a 3 amp load of the LED while being able to operate at voltages around 3V or 6V. It must be able to keep the LED on constantly while also being able to pulse the LED.
A 4.5-volt series circuit consists of two resistors. Resistor A has three times the resistance as resistor B. An ammeter records a current of 160 mA of current. Determine the resistance values of resistors A and B.
X1 and X2 are two independent Gaussian random variables each with mean zero and unit variance.
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
A temperature sensor has a static transfer function of 0.15mV/degrees C and a time constant of 3.3 s. If a step change of 22 degress C to 50 degress C is applied at t = 0, find the output voltages at 0.5s, 2.0s, 3.3 s, and 9s.
A three-phase load is Y-connected. The load has a phase voltage of 139 V and a phase current of 49 A. Each phase of the load consumes 5.1 kW of power. (A) Sketch and label the load. Find (b) the line voltage, (c) the line current, and
Design a passive RC low pass filter with a cutoff frequency of 100Hz using a 4.7 uF capacitor. a) draw a schematic showing your filter while designating all component values and labeling the input and output voltage
give three methods that are used to express logic relationship between inputs and outputs of a logic gate, for example a three-inputs NOR gate.
What is the sample period Ts?
