If we have a transfer function T(s) = |Z(s)|/|P(s)| and we had a pole at s=-500; Then the magnitude would be sqrt(500^2 + w). So how does that not decrease the magnitude of the transfer function at frequencies below 500?
Calculate the location of Ei in silicon at liquid nitrogen temperature(77k), at room temperature 300k and at 100 degree celsius (let mp =1.0mo and mn= .19m0) Is it reasonable to assume that Ei is the center of the forbidden gap
Due to its wider bandgap than silicon, a GaAs red light emitting diode (LED) typically has a turn-on voltage of 1.6 V. Assuming the maximum allowable current through the LED is 16.7 mA,
The messages being sent are 2 milliseconds long. Computer A starts sending a message on the bus; 250 microseconds later, Computer B starts to send a message, and 250 microseconds after that, Computer C starts to send a message.
c) Find the output y(t) in response to the input x(t) = 6 u(t), where u(t) is the unit step function. d) Find the output y(t) in response to the input x(t) = δ(t) A linear system has the system response function H(s)= -7/(s+4)
A lossless transmission line of electrical length l = 0.3? is terminated with a complex load impedance . Find the reflection coefficient at the load, the SWR on the line, the reflection coefficient at the input of the line
A power amplifier has a gain of 15db and an input level of 2 volts. Assumming that the input and output impedance are the same. What is the voltage level at the amplifier output.
Using a shorted stub to match load, what is the lenght of the line where the normalized input Y is 1 + jb . If the characteristic impedance of the shorted line is 40 ohms, what is the length of the stub length.
Design the counter using D-flip-flops such that the state codes are the output values of the circuit. For example, when the circuit is in state 011, the output LED's display "off" "on" "on". Thus, no output equations need to be designed.
Is the high carrier concentration in transparent conductors due to their ideal band structure or to the presence of defects and dopants. If two different materials but with the same work function are brought into contact, does band bending result.
implement a circuit that generates VGA signals to draw a blue screen on your monitor in a resolution of 640x480. The following materials provide detailed descriptions of how VGA signals operate and some hints on how to design the VGA controller
