One definition for the threshold level in a binary PCM system is a probability of error such that the S/N ratio is 1 dB below the quantization noise limited region. The probability of error in such a case is aboutAssume a binary PCM system in which the system ratio of the bit energy to the one-sided noise density at the receiver input is 10 dB. Assume that the probability of error for any value of the independent variable off the scale can be approximated as zero.
silicon is doped so that 1 in 10000 Si atoms is replaced by phosphorous atoms. A) Knowing that only 30% of the phosphorous atoms donate electrons at room temperature (30% ionization) , determine the effective doping level and electron concentratio..
Are these signals periodic, find their fundamental period T and their fundamental frequency, otherwise prove that they are non-periodic x(t)= 4 cos(12 t+400) + sin(16 t) x(t)=cos4t +3e-j12t x(t)= ej(10t+p/3) x(t)= ejt +ej3t +sin(6t)
The time has come for XelPharm to expand. The board of directors has purchased another warehouse for a second distribution facility. It's located in an industrial area, about eight miles from the company's headquarters.
Signal transduction refers to any process of changing one signal to signal of another type. An example would be a series of pulsing lights into the sound for the word: "Help". Discuss how this transduction could be done by a device.
A Fabry-Perot interferometer is to be used to resolve the mode structure of a He-Ne laser operating at 632.8 nm. The frequency separation between the modes is 150 MHz. The plates are separated by an air gap and have a reflectance of r^2=0.999.
A 12V-DC power supply that gets it's power from the 110V (RMS) wall outlet needs a transformer as a first step in generating its output. The rectification and regulation stage of the power supply needs an input voltage of 15V (peak)
The electric field in a region of space is E= 4 ax V/m and the magnetic flux density is B= 5 az Wb/m2. At t= 0 a particle with mass 1 kg and charge 1 C is located at the origin traveling at a velocity of u0= 10 ay m/s.
a) If the excitation voltage E0 is equal to the terminla voltage ( 4kV ), what is the maximum real power which the motor can deliver without losing synchronism b) What is the rotor pole shift in electrical degrees, corresponding to the nominal loa..
1. Find the transfer function 2. Find the Laplace transformation of the output when x(t)=sin(t)u(t) 3.Find the output by taking the inverse Laplace transform of part 2.
calculate the minimum sampling interval (time period for counting the pulse train) to achieve a speed resolution of 5 rpm, and the number of bits that must be there in the binary counter if the pulse train is to be sampled with this interval for a..
computation with 5% of the code that cannot be paralleled, compute the speedup and efficiency.
Finding peak amplitude, frequency, and spectrum shape, b. A signal generator outputs a unipolar square wave with a period of 0.50 ms and an amplitude of 2.0 V. The output of the generator is passed through an ideal band pass filter that has a pass..
