What is the minimum sampling rate that can be used to obtain samples that completely specify the following signalx(t) = 10cos(20*pi*t) - 5cos(100*pi*t) + 20cos(400*pi*t)
An engineer is required to survey a nonrectangular plot of land but is unable to measure side UT directly (see Figure 2.11). The following data are taken: RU=121.0m, RS=116.0m, ST=83.5m, angle RST= 113 degrees
a. Determine the voltage regulation, the load resistance, the armature resistance, and the developed torque at full load. b. The speed of the generator is decreased to 1200 rpm, and the load resistance is unchanged.
What approximate minimum BER is required for voice signals, data signals and what is the approximate BER level for the optical fiber systems ?
Interface binary Input Output devices to the microcontroller
How are the left (L) and right (R) signals obtained separately in the radio receiver to drive the dual channel audio amplifier and speakers?
Design a sequential Mealy circuit with two inputs A and B, and output X using JK flip-flops. The circuit produces an output X = 1 when it detects the sequence of either A = 00 or B = 11, otherwise X = 0.
A. Make a two bit counter with The input X =0 makes the counter count from 0-3-1-0 and X=1 goes from 0-1-2-3-0. Choose two different types of flip flops to implement it. B. Describe what will happen on your circuit when the present state is 2 and ..
(1) check a diode out with a regular ohm meter (2) Give an example of where a half wave, full wave or bridge rectifier is used. (3) What sizes of transformers are used for power lines
If someone presses the 1 or First floor button, the elevator should go to the 1st floor, open the door and remain in this state for a small amount of time, then close the door. Assume the elevator takes one clock cycle to travel.
where the assigned loop current leaves the voltage source. If current leaves the voltage source at its positive terminal, the voltage would be positive and if it leaves the voltage source at its negative terminal,the voltage would be negative.
Compare the differences in the FFT result. Explain why even though the inputs to both FFTs are the same cosine waves, the shapes of the FFTs are different. Calculate, plot and compare the results of the 512-point FFT of the above signal.
The output power of the digital transmitter is 0 dBm and the link has a constant attenuation of 50.0 dB. At the input to the receiver, the equivalent AWGN noise power is – 70 dBm. Assume implementation margin is 0 dB when calculating BER in ..
