Suppose we measure the noise in a resistor (with no applied voltage) and find that the noise voltage exceeds 10 μV 5% of the time.
We have reason to believe the noise is well modeled as a Gaussian random variable, and furthermore, we expect the noise to be positive and negative equally often so we take the parameter,σ2 , in the Gaussian PDF to be m =O .
Find the value of the parameter, . What units should be associated with in this case.
Determine the strength of a uniform electric field if it is to have the same energy as that established by a magnetic field of flux density 0.8 T. Assume that the relative permeability of the magnetic field and the relative permittivity of the ele..
Consider a myelinated fiber in which th nodes of Ranvier are spaced every 2mm. The resistance of the axoplasm per unit length is r(initial) = 1.4x10^10 omega/m. The nodal capacitance is about 1.5x10^-12 F.
Using a 50-µA, 1000-Ω d'Arsonval movement, design a multi range milliammeter having scales of 25 mA, 50 mA, and 100 mA. - Show the circuit and component values.

Calculate and plot the resulting noise figure as the input reflection coefficient magnitude, ||, varies from 0 to 0.9 for F = 1, 3, and 10 dB.
what are two fundamental advances in the circuit theory that were developed in the 19th century in response to the challenges of telegraphy?
A voltage of 100 VDC is applied across a resistor, and the temperature of the resistor is measured. Which of the voltage waveforms shown in the figure, when applied across the resistor, would produce that same temperature - What is the value of t..
A generator is rated at 500 MVA (three phase) and 22 kV (line-to-line). Its Y-connected windings have a reactance of 1.1 per unit. Find the ohmic value of the reactance of the windings. What is the per unit value if we change the base to 200 MVA a..
1.Write a single line Verilog statement that declares a 12-bit by16-word memory called mem1. 2. Write a single line Verilog statement that assigns the fifth word of mem1 the decimal value 127 on the positive edge of the signal clock.
In a motor control system, one master stop pushbutton (Stop) is available for stopping the operation at any time. If the temperature switch (TSW) is closed, pressing the red pushbutton (RedPB) will turn on both motors M1 and M2.
A finite state recognizer or sequence detector has one input (X) and one output (Z). The output is asserted high (Z=1) whenever the input sequence 1101 has been observed during the past four clock cycles, as long as 1110 has never been observed.
