The 24-bit data field of a packet is given by 0xBC603F. The packet contains a CRC with the generator polynomial given by X
3+X+1
a) Find the CRC checksum. Provide the complete code-word including the checksum in hex.
b) A burst error of the form 0x00F0000 is induced due to noise during packet transmission.
Write the received codeword. Is this error detected by the receiver?
c) Repeat b) if the error vector is given by 0x00BB000.
The signal to noise ratio at the receiver is required to be at least 17 dB. The average noise power at the receiver is 1 mW. The cable loss between the transmitter and the receiver is 2.5 dB/km
assuming XTAL=11.0592 MHz,write a program to genrate a square wave of 20 Hz frequency on pin2.3?
Transmit this data wirelessly to a base station for storage. How much bandwidth would you need.
Design a counter to count even numbers between 0 and 15. Therefore states will be 0 -> 2 -> 4 -> 6 -> 8 -> 10 -> 12 -> 14 -> 0. If any unused state is encountered bewteen 0 and 7, then the counter should go back to initial state 0.
Determine whether the Boolean funcions F=a'c+ab'c+ab and G=b'c+a'bc+abc+ab are equivalent using algebraic manipulation.
The system uses a 7-cell reuse pattern. If the offered traffic per user is 0.03 Erlangs and the average number of calls per hour per user is 1.5, for an Erlang-C system with a probability of delaying a call being 5%, calculate the traffic load per..
n the conduction band of a semiconductor, it has a lower valley at the center of the Bril- louin zone, and six upper valleys at the zone boundary along [100]. If the effective mass for the lower valley is 0.1m0 and that for the upper valleys
Compute and plot the correlation sequences r s1s2 (l), r s0s0 (l), r s1s0 (l) and r s2s0 (l) . Compute and plot the cross-correlation sequences and of the received signal with the template signals and s 2 (n).
What is the attenuation per octave between 1 kHz and 10 kHz? What is the increase in attenuation between 5 kHz and 10 kHz?
A new semiconductor has Nc = 1019 /cm3 and Nv=5 x 1018, and Eg = 2eV. If it is doped with 1017 donors (fully ionized), calculate the electron, hole, and intrinsic carrier concentrations at 627K.
(a) Determine a unit vector in the direction of Q at P(1, 2, 1) (b) Find the component of Q at P in the direction of PT where T is point (5, 3, -4) (c) Where is Q the same as the unit vector of \(a_{x}+11a_{y}+10a_{z}\)
Select an appropriate QAM signal constellation, carrier frequency, and the roll-off factor of a pulse with a raised cosine spectrum that utilizes the entire frequency band. Sketch the system block diagram and the spectrum of the transmitted signal..
