Digital Encoding(Encoding) To digitally manipulate information we must encode it using binary numbers. Consider an encoding for playing cards. There are 52 cards in a deck and they are divided into four suits with values from 1 to 13 (an Ace is 1, Jack is 11, Queen is 12, King is 13). Show two possible encodings for the cards.
What is the maximum bandwidth of the low pass filters at the receiving end of the link? What bandwidth would you recommend for the LPFs?
Write a brief explanation of the principles of the super-heterodyne receiver. It may help to use a simple block diagram to express the process. Explain the purpose of the Intermediate Frequency amplifiers,
Discrete sequence plot in Matlab, Consider the following formula, x[n] = x[n-1] + x[n-3] n>=3, find the rest of the sequence for 0
Finding the periodicity in N of the discrete time signal x(n) = Cos(3pi*Ts.n + pi/4) and then plotting the discrete signal. From this the condition on the sampling period is determined
Give three advantages of a three-phase system over a single-phase system There are two basic three-phase connections, the wye connection and the delta connection. Draw a labelled diagram showing the wye connection
Rain affects the downlink from the satellite and the overall CNR ratio in the receiver falls by 6.0 dB to 13.0 dB. What is the bit error rate and the time between errors now?
A time varying capacitor is characterized by the charge- voltage equation q(t) = C(t)v(t)
Determine power series values for common scientific and engineering functions and Obtain the Maclaurin series for the following functions. State the values of the x which the series converge.
Determine the energy uses on farms in middle east and determine whether or not it is better to use a stand alone system or a grid connected system for the application on farms.
An LVDT is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31mV/mm with +/-2cm maximum core displacement.
The purpose of this project is to design a device that would remotely control (from a Bluetooth-enabled mobile phone for instance) at least two actuators (e.g. relays and switches).
Calculate the %age second harmonic distortion present in the amplifier's output for a sinusoidal input of 10 mV r.m.s.
