The following heat engines produce power of 95,000 kW. Determine in each case the rates at which heat is absorbed from the hot reservoir and discarded to the cold reservoir.
A Carnot engine operates between heat reservoirs at 750 K and 300 K.A practical engine operates between the same heat reservoirs but with a thermal efficiency h = 0.35.
What is correct symbol rate (pulse rate) for this link? What is the bit rate with BPSK modulation? What is the bit rate with QPSK modulation?
Linearity, order, casuality, and time variance for systems, What are the linearity, order, casuality, and time variance of each input-output relationship for systems?
In order to eliminate the cost of calling cards, the company in the above problem is considering a new policy that requires blocked callers to redial over and over until they get a trunk.
Modify the state diagram branching conditions in the diagrams below as needed to ensure the sum and exclusion rules are obeyed in each case.
Using coppers resistivity of 10.30 CM-olm/ft at +25 °C, find how long a 1 inch square bar of copper would need be to have a resistance of 1 at +20 °C
Understanding low, high and band pass filters, A signal in the IF section of an FM radio receiver occupies the frequency band 10.61 MHz to 10.79 MHz. Compute the bandwidth of this signal.
What is the difference between multiplexing and multiple access?
Sketch the Capacitance-Voltage characteristics for both devices based on part (d) by giving appropriate labeling to the voltage and capacitance axis. You may assume high f measurements.
Draw a labeled sketch of x(t) over a few periods: be careful, make sure you follow the exact definition of x(t)
Bode plots were introduced in my second circuit analysis class, but I really didn't think it was important because it looked like an outdated tool no longer in use.
Write down the principle of energy conversion and give an example for single and double excited system.
Consider an LTI system with impusle response h(t) = e^(-.2t)*(u(t-1)-u(tt-8)) a) plot h(t - tau) for various values, make sure you show how the parameter t influences the position of the curve in the graph. b)Find the output y when the input is x(t) ..
