A logic 0 is transmitted at a nominal level of -1.0 V, and a logic 1 is transmitted at a nominal level of 1.0 V. If a 250-mV RMS Gaussian noise signal is assumed to be present at the receiver, what is the probability of making an single trial bit error if the detector threshold is set at 0.0 V. Assume that a logic one has twice the probability of being transmitted than a logic zero
Show that there are by developing an algorithm to generate them in base R, and use algebra to show that numbers generated by your algorithm will have the digit-reversing property. Then generate examples in binary
The factorial n! of a positive number (integer) is defined by n! = n.(n-1).(n-2)...3.2.1, where 0! = 1. Write a user-defined function that calculates the factorial n! of a number. For function name and arguments use y=fact(x)
Draw a circuit model of the path of current through the human body for a person touching a voltage source with both hands who has both feet at the same potential as the negative terminal of the voltage source.
Why can't a video signal such as an NTSC analog television signal be transmitted over a two km length of loaded twisted pair cable with a frequency range 300 Hz to 3,400 Hz? What is the bandwidth occupied by an NTSC video signal?
Given and airplane whose velocity relative to air (airspeed)is 120 km/hr (heading), the direction of the velocity vector is 70degrees east of north. Velocity relative to ground(groundspeed) is 110 km/hr (course)
A cylindrical brass sleeve is to be shrink-fitted over a brass shaft whose diameter is 3.216 cm at 0°C. The diameter of the sleeve is 3.203 cm at 0°C. (a) To what temperature must the sleeve be heated before it will slip over the shaft

An electric field of 3.10×105 is desired between two parallel plates, each of area 36.0 and separated by 0.620 of air.What charge must be on each plate?
A PN flip-flop has four operations, clear to 0, no change,complement, and set to 1, when inputs P and N are 00, 01, 10, and11, respectively. (a) Tabulate the characteristic table. (b) Derive the characteristic equation.
an unknown semiconductor has Eg=1.1ev and Nv=Nc.it is doped with 10^15 donors,where the donor level is 0.2ev below Ec. given that Ef is 0.25ev below Ec, calculate ni and the concentration of electrons and holes in the semiconductor at 300k.
Consider a continuous-time LTI system with frequency response of H(j omega) = 1 + j 250 omega/(2 - j 50 omega)2 Find the expression for the magnitude of H(j omega) and sketch its Bode plot (sketch asymptotes and the magnitude curves).
Determine the capacitance as a function of Ri and Ro. If the dielectric is polystyrene of relative permittivity, εr = 2.6, calculate the capacitance of an isolated conducting sphere of a radius 0.4cm(i.e., Ri=0.4cm and Ro goes to infinity).
