Consider a 16-ary PSK system with symbol error probability PE = 10-5. A Gray code is used for the symbol to bit assignment. What is the approximate bit error probability?
causal LTI discrete system whose transfer function is given by: (H(z) = (z - 0.5) / ((z-e^{ln(0.16/z)})(z-0.2))\) find the impulse response sequence, h[k], for all k. Check initial and final values of the impulse response sequence using appropriate m..
1. Use the Quine-McCluskey minimization method to find a minimum cost SOP realization of the following functions (a) f(x1,x2,x3,x4)= fm(0,2,4,5,7,8,9,15) (b) f(x1,x2,x3,x4)= fm(0,4,6,8,9,15) + d(3,7,11,13)
A MOS differential amplifier is designed to have a differential gain Ad equal to the voltage gain obtained from a common-source amplifier. Both amplifiers utilize the same values of RD and supply voltages, and all the transistors have the same W/L..
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
Using the LM555 data sheet, make an estimate of the maximum fundamental operating frequency in the astable mode.
consider a fax/xerox outlet, processin files of various size. the size (in number of pages) of the files to be faxed or xeroxed has a geometric (p) and poisson (a) PMFs respectively. An arbitrary file arriving at the outlet is a fax file with prob..
Construct the adder for 2 digit decimal numbers presented in BCD code. 4 bit binary adders and additional logical gates. The BCD adder for each decimal digit can be implemented with two 4 bit binary adders where the second adder.
