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?
Write a Matlab program to calculate the electric field due to a line of charge of length 1m. a) Describe the line of charge as a collection of point charges centered on the z-axis. Calculate the electric scalar potential of that same line of charge.
The Arrhenius equation is used to explain the dependance of the reaction rate coefficient, k, on temperature, T. Linearize the Arrhenius equation for the the temperature dependance of chemical reaction rate coefficients.
Construct a 2 rung ladder schematice with an AC source with overload protection in the main line, the schematic will contain 1 rung with a lamp load controlled by a N.O. Push button. On the second rung there will be a N.C.
Design a circuit to multiply a 2-bit unsigned magnitude binary number by 1, 2, 3, or 4 to produce a 4-bit output
Use MATLAB to determine and plot the step response of the digital filter for several time constants. Use the time constant of part (b) and fs = 500Hz. Compare the results of parts (b) and (c).
A 120 kVA transformer is to be parallelled to a 60 kVA transformer. Each transformer has rated voltages of 10kV-120V at 60Hz. When supplying a 250A load at 0.85 PF, what is the total input current and power factor if the output terminal voltage is 12..
A saturated npn transistor has a base to emitter applied voltage of 0.6V. The collector to emitter voltage is 0.2V. The collector current is 12mA
What do you believe would happen, if you removed the 220 ohm resistor from the circuit and connected the LED directly to the 555 integrated circuit. Are there any appreciable differences between labeled, calculated.
An optical communication system employs a photodetector whose output is modeled as a Poisson(λ ) random variable X. Find the second moment and the variance of X.
