A telephone line has the following parameters: R = 40 W/m, G = 400 mS/m, L = 0.2 mH/m, C = 0.5 nF/m. (a) If the line operates at 10 MHz, calculate the characteristic impedance Zo and velocity u,
Willy has also noticed that the power supply has a current limit that can be set. When he sets the current limit to 8 amperes, it provides exactly 8 amperes, but it doesn't overheat, so it's not shu
Suppose we have a causal LTI system with rational system function H(s). We don't know H(s), but we do have the following information: i. When the input to the system is x(t) = u(t), the output y(t) i
A cable technician tested the signal-to-noise ratio on the curb as 20 dBm. This means, if the noise power is at 1 mW, then the signal power should be 20 dB higher then that. If the noise power is 20
Germanium is n-type doped at 5x1015 cm-3 at T=300 K. The dimensions of the Hall device are d=5x10-3 cm, W=2x10-2 cm, and L=10-1 cm. The current is Ix=250 A, the applied voltage is Vx=100 mV, and the
A constant electric field, E=12 V/cm, exists in the +x direction of an n-type gallium arsenide semiconductor for . The total current density is constant and is equal to 100 A/cm2. At x=0, the drift
The signal given is x(t) =cos(440*2*pi*t) +cos(554*2*pi*t)+cos(659*2*pi*t) Find the complex exponential forier series of the signal and plot k vs Ck for k=-1000 to 1000.
