Determine the minimum bandwidth, baud, and bandwidth efficiency for the following bit rates and modulation schemes - 8-QAM and 16-QAM.
Fb = 2400 bpsFb = 4800 bpsFb = 9600 bps
Telephone channels have a bandwidth of about 3.1khz. do the following in excel. A) If a telephone channel signal to noise ratio is 1000, how fast can a telephone channel carry data?
A pulsar lies 1000 light years from Earth. The average plasma concentration is 1 el/cc. Using the plasma dispersion relationship for group speed, what is the group delay between a pulsar pulse received at 1 GHz and at 800 MHz
Implement a high-speed multiplier which will multiply two 2-bit binary numbers (B1B0 and C1C0) using a 16X4 PROM (lookup table implementation). List the content of all the memory locations in the PROM and describe the operation.
A radio receiver has a noise power N = kTB watts, with T = 100 K and B = 1.0 MHz. The value of k is 1.38 x 10^-23 J/K. What is the noise power in dBW?
A telephone switching board can handle 120 phones. Assuming the following, and determine the outgoing traffic intensity and the number of channels
write an 8051 program that would generate a 200khz, 50% duty cycle, square wave at P1.0.Use Timer 0 for the delay. Ignore the overheads cycles due to the instructions in the loop. Assume 12 MHz clock. All data must be hex.
What is the impedance of a resistor R in parallel with a series combination of a capacitor C and an inductor L? Assume angular frequency omega(w).
Determine the voltage required on the input of the amplifier to give the maximum output of 85 dBuV. If the signal level from the aerial is 5 dBmV and the input noise level is 20 dBuV, calculate the signal-to-noise ratio on the output of the amplifi..
The signal transmitted by a Base Station has a power of 1 mW at a distance of 1 m from the transmitter. Measurements have shown that the propagation exponent for the path loss is n=3 up to a distance of 1 km and n=4 beyond that.
Important information about Noise, Explain the role of the central limit theorem in the behavior of Additive White Gaussian Noise (AWGN).
At the end, the wave totally reflects with a pi phase shift, and the reflected wave now interferes with the incident wave to yield a standing wave pattern over the line length.a) Determine the standing wave pattern for the voltage in the line.
