A band limited randomsignal of band width 10kHz is uniformly distributed over the range(-1,+1) VOLT, it is sampled at twice Nyquist rate and quantizedinto Q levels. The samples are binary PCM encoded into n bits whichare transmitted using two waveforms S1 (t)=1.414 sin(w1t) and S2(t)=1.414 sin(w1t) + 1.414 cos(w1t) where t is between 0 and Tb,and the a priory probability of S1 is p(s1) = 0.4. Abinary matchedfilter receiver is used and a WGN is added with No=E(-7)w/Hz.a) Find the number of binary digits n required to have BER=E(-4)b) find the ratio of message signal power of m(t)to the noise output due to channel error and quantization error indB.c) Find the signal to qunatization error ratio, and signal to channelerror ratio and comment.d) Suggest a minimum modification for the waveforms to gain some advantages for the same error probability, and specify thisadvantages. Find also the effect of this modification on the resultobtained in (b) above.
A pulse is used to measure the frequency response of a system. Since we expect the frequency response to extend to 20 kHz, we want to select a pulse whose magnitude spectrum is constant within 1% out to 20 kHz.
1.)An op amp requires the design equation Vout = 5Vin & 2Vref + AgVg. What is the value of Ag 2.)The voltage dropout of a voltage regulator is 1.6 V. If a 16 V output is required, what is the minimum regulator input voltage
A 480-120 volt, 5kVA, 2-winding transformer is to be used as an autotransformer to supply a 480-volt circuit from a 600-volt source. When tested as a 2-winding transformer at rated load, 0.8 pf lagging, its efficiency is 0.965.
design an IIR high-pass filter using bilinear method in a system with sampling frequency of 100 Hz. The lower and higher cutoff frequencies are at 18 Hz and 35 Hz respectively. Pre-warp the cutoff frequencies.
Construct the straight line Bode plot of the gain. Is this a low-pass, high-pass, bandpass, or bandstop function Estimate the cutoff frequency and the passband gain. Note that s = jw. This problem uses the letter T for system function.
A battery has a short-circuit current of 20 A and an open-circuit voltage of 12 V. If the battery is connected to an electric bulb of resistance 2 ohm, calculate the power dissipated by the bulb.
A conservative design team C and an innovative design team I are asked to separately design a new product within a month. From past experience, we know The probability that team I is successful is 1/2 The probability that one and exactly one team..
A charged 100- picoFarad capacitor has initial voltage across it of 10 V. A 100 kohm resistor is suddenly connected across the capacitor (at t=0) to discharge it. What is the magnitude of the instantaneous current at 20 usec
Design a 3-bit Incrementer/decrementer use btn_west as incrementer, i.e. when pressed, count increments by 1 use btn_east as decrementer, i.e. when pressed, count decrements by 1 use btn_south as reset, i.e. when pressed the count is resetted to 0.
A police K-band radar is operating, with transmit power of 1000 Watts and antenna gain of 300 in linear units. The radar unit is designed to detect a target with a radar cross-section (RCS) of 6 sq. meters and its receiver can detect a signal
Write a C program for the 68HCS12 microcontroller to send the pattern 0x55 to byte-sized Memory Location "OUT1" and then call a delay function. The delay function should generate a delay of two milliseconds.
a parallel plate transmission line is made up of perfect conductors of width w = .2m and d = .01m. The medium between the plates is a diaelectric of epsilon = 2.25*(epsilon not) and mu = mu not. For a uniform plane wave propagating down the line
