Performance evaluation of seismic data quantization:
The seismic signal, a measurement of the acceleration of ground motion, is required for applications in the study of geophysics. The seismic signal ("seismic.dat" provided by the US Geological Survey, Albuquerque Seismological Laboratory) has a sampling rate of 15 Hz with 6,700 data samples, and each sample is encoded using 32 bits. Quantizing each 32-bit sample down to the lower number of bits per sample can reduce the memory storage requirement with the trade-off of reduced signal quality. Use Programs 2.3 to 2.5 and modify Program 2.2 to quantize the seismic data using 13, 15, 17, ., 31 bits. The SNR in dB must be measured for each quantization. Create a plot of the measured SNR (dB) versus the number of bits. For comparison, plot the seismic data and the quantized one using 13 bits, 18 bits, 25 bits, and 31 bits.
Water is the working fluid in an ideal Rankine cycle. Superheated vapor enters the turbine at 10 MPa, 4808C, and the condenser pressure is 6 kPa. Determine for the cycle the rate of heat transfer to the working fluid passing through the steam generat..

Determine the Thevenin equivalent of the network shown on the left and determine the current - determine the complex power generated by the (ideal) 400V source.
List three standard socket calls that you would expect every connection-oriented server to invoke that would not normally be invoked by any client. Briefy indicate why a typical client would not need to invoke these calls.
Your selection shall be based on a life cycle cost analysis (LCCA) including PW and EAC. Be sure to show complete functional notation with the correct compound interest factors for each option
Modulation increases transmission range. I thought that main reason for modulation is antenna size and sharing of common channel via FDM. I can't get the reason behind the range extension? Can anyone help me in that regard?
Determine which of these properties hold and which do not hold for each of the following continuous-time systems. Justify your answers. In each example, y(t) denotes the system output and x(t) is the system input.
Develop with MATLAB, a fuzzy control system for controlling the power of a motor (0-350 rpm) based on the supported load (0-1700 lbs) thereby that at greater load develops more power. The system must contain at least 5 rules, but preferably 7.
A two stage counter has two input, M and N. (a) Design a counter assuming the outputs come directly from J-K flipflops. (b) Design the counter assuming a two-stage binary counter is used with the J-K flipflops outputs decoded.
