the signal x(t) = e^ -|t|
(A) Plot the singal x(t) and determine if this signal is finite energy. That is compute the integral and deretmine if it is finite.
(B) If you determine that x(t) is absolutely integrable or that the integral is finite, could you say that s(t) has finite energy? Explain why or why not. HINT:Plot |x(t)| and |x(t)|^2 as functions of time.
(C) from your results above, is it ture the enegry of this signal y(t) = e^-t cos (2*pi*t)u(t) is less than half the energy of x(t)? Explain. to varify your result use symbolic Matlab to plot y(t) and compute its energy.
(d) to discharge a capacitor of 1mF charged with a voltage of 1 volt we connect it, at time t = 0, with a esistor of R ohm. When we measure the voltage we find it to be V(r) (t) = e ^(-t) u(t). Determinethe resistance of R. If the capacitor has a capacitance of 1 microF, what would be R? in general how are R and C related?
Gold cost about $100 an ounce in 1971. In 2007, the cost of an ounce of gold is hovering around $800. compute the average price increase for gold.
In most situations it is also desirable to send information from the process to be controlled--in this case the 500-gallon tank--to a central station for processing and storage. This information can be transmitted and processed in different ways.
The solutions to Schrodinger's wave equation for a particular situation is given by Psi(x) = sqrt(2/ao)*e^-x/ao. Determine the probability of finding the particle between the following limits: (a) 0
A transmitter is using a 2B1Q and operating at 3 Mbps. What is the minimum bandwidth necessary on the transmission line for successful communication
What value of emitter resistor would you choose, if: a) You have to amplify the signal of a microphone that has an internal resistance of 100K using a Common Emitter bias configuration b) you have to drive a load of 50 with an Emitter Follower cir..
An odd parity circuit with 2^n inputs can be built with 2^n-1 XOR gates. Describe two different structures for this circuit, one of which gives minimum worst-case input to output propagation delay and the other of which gives a maximum.
A proportional controller for a rotating antenna has a gain Kp of 5 in-oz/deg. The antenna was initially pointing due south, but was then commanded to point southeast. Find the initial torque supplied to the antenna.
A thin metal disk of mass m=2.00 x 10^-3 kg and radius R=2.20cm is attached at its center to a long fiber. When the disk is turned from the relaxed state through a small angle theta, the torque exerted by the fiber on the disk is proportional to t..
A long hallway has three doors, one at each end and one in the middle. A switch is located at each door to operate the incandescent lights along the hallway. Label the switches A, B, and C.
An n-type piece of silicon with a length of .21um and a cross section area of .05x.05 um sustains a voltage difference of 1V. If the doping level is 10^17 cm^-3, Calculate total current flowing through the device at 300K
1. The current in a circuit is 1 amp. What will the current be when the voltage is increased by 50% 2. A 10ohm resistor is connected across a 12 V battery. How much current is there through the resistor
A standard 12-V car battery has an ampere-hour rating of 30 Ah, whereas a heavy-duty battery has rating of 51 Ah. Calculate the ratio of available energy and the percentage increase in available current for starting.
