design a 4 bit register with 4 different kinds of flip flops, that has at least 12 different functions. list clearly the functions. Do something creative, and say exactly your innovation. at least one flip flop should have some input besides a multiplexer
Select an appropriate QAM signal constellation, carrier frequency, and the roll-off factor of a pulse with a raised cosine spectrum that utilizes the entire frequency band. Sketch the system block diagram and the spectrum of the transmitted signal..
a resistor is required for an application that requires its value to be no less than 7.1k ohms and not more than 7.9k ohms. determine the nominal value and the maximum tolerance of the resistor you could use. explain.
Let x[n], y[n] and w[n] denote three finite-lenght sequences of lenghts N, M, and L, respectively with the first sample of each sequence occuring at n=0. What is the lenght of the sequence x[n] * y[n] * w[n]
3) What is the RMS voltage of the source in a single loop series circuit if Irms = 1A-30° and Ztotal = 100 65° 4) What is the power dissipated by an electric heater with a resistance of 20? drawing a current waveform of i(t) = 10 sin(60t) Amps
discuss the differences between FET and BJT transistors. What are the advantages and disadvantages of each kind of transistor What are types of transistors do you know about
Silicon has an absorption co-efficient of 850 cm-1 at a wavelength of 805 nm. Light of intensity 1 W/m2 at this wavelength is directed at normal incidence onto a polished silicon wafer of thickness 0.5 mm.a. Assuming a top surface reflectance of 30..
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
Transmitting data at higher speeds generally requires a wider bandwidth, which is not always possible within FCC guidelines. In addition to the wider bandwidth, higher speed transmission also requires a higher transmit power. Why
Design a combinational circuit with four inputs, x,y,w, and z, and four outputs: A, B, C, and D. When the binary input value in decimal is 3,5,6,9,10 or 12, the binary output value is one less than the input value, otherwise it is one greater than..
An FM signal being transmitted is represented by eFM(t) = 50Sin((2)(95.1)(106)t+2Sin((2)(10)(103)t)). If the antenna impedance is 75 , determine: (a) total power in FM signal and (b) FM modulation index.
a.) What isthe minimum sampling frequency to avoid aliasing b.)If the sampling frequency of fs=2500 samples/sec is used how many samples must be taken to give a frequency resolution of 10Hz
Draw a strain gauge circuit and its external components to attach to a conveyor mounted only at the ends to measure the load at the center of the conveyor. What type of testing would you need to do to establish a baseline and calibration curve for..
