A three-level PAM system is used to transmit the output of a memoryless ternary source whose rate is 2000 symbols/sec. The signal constellation is shown in Figure P-8.34. Determine the input to the detector, the optimum threshold that minimizes the average probability of error, and the average probability of error.
The highest frequency component of high-fidelity sound is 20 kHz. If 16 bits are used to encode the quantized signal, what bandwidth is needed as a minimum for the digital signal?
A small businessman planes to start a taxi -service and purchased a new car for #36000 with borrowed money at 15% compounded annually , his net income is $12000 per year and the salvage value of the car at the end of 4 years is $5000.
Design a self-test circuit, similar to Figure 10-25, for a 6116 static RAM (see Figure 8-15). The write-data generator should store data in the following sequence: 00000000, 10000000, 11000000, ..., 11111111, 01111111, 00111111, ..., 00000000.
1.Given S-DOman transfer function H1(s)= 1/(s+2). What is the time response H1(t). 2. Given H2(s)= (2s+5)/(s^2 +3S+2), what is h2(t) 3. Calculate the data value and address location for the following 8-bits date: 01111011 Buss address 10110011
Write a software that programs counter 2 to generate an 80 KHz square wave if the CLK input to counter 2 is 8MHZ.
Two stations running TCP/IP are engaged in transferring a file. This file is 104KB long, the payload size is 100 bytes, and the negotiated window size is 2000 bytes. The sender receives an ACK 900 from the receiver.
Find the current in a ground loop that is 200 ft long, has a wire resistance of 0.05 ohms/ft, and has a difference of 4 V between grounds.
The spheres have positive charges. The spheres are in equilibrium and each rope makes an angle 30 degrees with the vertical. Find the tension of the ropes.
Send no pulse for the stop speed. Some additional mechanical noise will result from pulsing the motors at slow speeds. See if the robot will move in a straight line at a slow speed.
A communications channel has a bandwidth of 2,000 Hz and a signal-to noise-ratio (SNR) of 20 dB. What is the maximum possible data rate
The maximum ripple allowed is Vr =0.5 V . In your desingn provide information about the transformaerturn ratio "n", filter capacitor "C" , PIV of the diodes and htethe peak current through the diode DA. Assume that the FBdiode , voltage drop is 1 ..
A R-C high-pass filter contains a 1 µF capacitor and a 1k resistor. Suppose a single "square" voltage pulse of 5 V for 1 ms duration is applied to the input. Carefully and neatly sketch the resulting output, including numeric values, of output volt..
