A 75-ohms lossless transmission line is terminated in a load ZL = 80+j60. The line is length lamda/8 long and connected to a line Z0= 50-ohms. What is the input impedance on the 50-ohms line, lamda/8 from the junction
What observations can be made about a physical system that has both pole and zero locations that are not real-valued or complex conjugate pairs.
A square metal plate is heated to 80 degrees celsius at the corner corresponding to x = y = 1. The temperature distribution in the plate is described by T = 80e^(-(x-1)^2)*e^(-3(y-1)^2) Obtain the surface and contour plots for the temperature.
For each of the sinusoidal source functions, determine the complex exponential source that has the given source as its imaginary part. Determine the phasor representation of each of the sinusoidal source functions.
Indicate the use of each memory in the microcontroller (HCS12). In other words, state which one is used for code, program variables, and variables that must remain when the power is turned off.
What are the filter gains for the stopband at the cut-off frequency and 500 Hz, and passband at 3000 Hz based on the plot of the magnitude frequency response. Print the highpass IIR filter coefficients and plot the frequency responses using MATLAB..
