calculate the impulse of an ideal filter with cut-off frequency of a)2KHz, and b)3KHz for a signal sampled with a rate 8000 samples/sec.
Simulating shadow fading. Simulate a sample path of a shadow fading process for equispaced samples on a straight line. Assume a correlation distance Dc = 500 m and a standard deviation of σz = 7.5 dB (these values are from Gudmundson's paper).
A WLAN uses the 1-Mbps IEEE 802.11 infrared standard and the 16-PPM modulation scheme. Compute the period of transmission (time between bits).
Create a non-inverting op amp circuit to obtain Vout = 12 V if R2 (RF) = 1100k-ohm and Vin =1V . Open up the attributes window of the op amp (click on the op amp symbol) and verify that VPOS = +15V and VNEG = -15V. Do not change any other attribut..
If the temperature remains constant and the external currentlI increases, what happens to the size of the depletion region Why
A 1 A diode can deliver 1 A up to 75ºC with a derating factor of 8.5 mA/ ºC (this means that the current must be reduced by 8.5 mA for each degree above 75ºC). How much current can be drawn at 110 ºC
Let x(t) = u(t) u(t 1).Find the average signal y(t) using the above integral. Let T = 1. Carefully plot y(t).Verify your result by graphically computing the convolution of x(t) and the impulse response h(t) of the averager.
A potentiometer with a total range of 350° is supplied with a voltage of 12 Vdc. Find the output voltage for an angle of 135°. An absolute optical rotary encoder has five tracks. How many bits is the output
Asssume that you are to design a synchronous TDM carrier to support 30 voice channels using 6-bit samples and structure similar toT1.Determine required bit rate
Explain how primitive values like doubles are passed between functions in Java. How are string objects passed between functions in Java How are static methods different from non-static methods How do you invoke a static method
Design a circuit containing a single op amp that can perform the following operation: Vo= 3x10^4(i2-i1), where i2 and i1 are input current sources.
A separately excited DC motor runs at1500 rpm under no load with 200 V applied to the armature.The field voltage is maintain at its rated value. The speed of the motor, when it delivers a torque of 5 Nm ,is 1400 rpm.
Design a circuit using an 8-to-1 multiplexer that functions as a 4bit odd parity generator. An odd parity generator outputs 1 if andonly if an even number of inputs are high.
