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.
Referring to the information above, if one were to sum all of the different average power values associated with the carrier and all sidebands, determine the total value of average power (in watts).

If a cache being simulated were allowed to have a block size of 4 bytes, what optimization would be possible for blocks of that size that is not possible for block sizes 8 bytes and above
Consider the non-inverting op-amp seen in class, but with a non ideal op-amp that has a finite gain Aod. Determine the expression of the output node potential as a function of the input node potential.
Box 1 contains 5 red, 6 white, and 9 blue balls. Box 2 contains 7 red, 8 white, and 4 blue balls. A ball is withdrawn at random from Box 1 and placed in Box 2. Then, a ball is taken at random from Box 2.
