Given a relay-user link as described in Section A.3 with the following parameters:
a. Find the received signal power level at the user in dBW.
b. Find the receiver noise level in dBW.
c. Compute the SNR at the receiver in decibels. d. Find the average probability of error for the following digital signaling methods:
(1) BPSK,
(2) binary DPSK,
(3) binary no coherent FSK,
(4) QPSK.4
(b) Verify that there are 4.994×(10 to the power 22) atoms per cubic centimeter in the Si lattice at room temperature. (c) Determine the center to center distance between nearest neighbours in the Si lattice.
During four consecutive clock pulses, a sequence of four values of the x signal is applied. Derive a state table for the FSM that produces z = 1 when it detects that either the sequence 1001 or 0111 has been applied; otherwise, z = 0. After the fo..
A Barangay power station supplies 60kW to a load over2,500 ft, 100 mm2, two conductors copper feeder, theresistance of which is 0.078 Ω per 1000ft. The bus bar voltageis maintained constant at 600 V. Determine the load current.
Which transistor bias circuit arrangement provides good Q-point stability, but requires both positive and negative supply voltages.
Create a circuit of three level sensitive D latches connected in series(the output of one is connected to the input of the next). Use a timing diagram to show how a clock with a long high time can cause the value at the input the first D latch
An air-standard Otto cycle has a compression ration of 9. At the beggining of compression, p1=100 kPa and T1= 300K. The heat addition per unit mass of air is 1350kJ/Kg. Determine. a) the net work, in kJ of air. b) the thermal efficiency of the cyc..
The speech quality for a particular mobile communication system is just acceptable when the received power at the terminals of the mobile receiver is -104 dBm. Find the maximum acceptable propagation loss for the system, given that the transmit po..
A measurement signal has a frequency less than 1 kHz, but there is unwanted noise at about 1 MHz. Design a low-pass filter that attenuates the noise to 1%. What is the effect on the measurement signal at its maximum of 1 kHz
Consider the step responses of two different imaging systems, one with a circular aperture of diameter 2ω and the second with a square aperture of width 2ω, with one edge of the aperture parallel with the edge of the step.
Using verilog hardware descriptional language or vhdl create a non-expandable dataflow description of a 2-bit magnitude comparator, from that create a behavioral dataflow description to create an expandable 2-bit magnitude comparator
(a) Calculate the length of the blades of a 1 MW wind turbine. Assume the air density is 1.0 kg/m^3, average wind speed is 15 m/sec, and overall efficiency is 25%. (b) An ideal solar cell is operating at30°C. The reverse saturation curren is0.15 mi..
With respect to sinusoidal signals, explain the difference between the way we normally define "amplitude" and the "amplitude" measurement on an oscilloscope. Also, How does the amplitude setting on a function generator relate to these
