A speech signal has a bandwidth of 3 kHz and an rms voltage of 1 V. This signal exists in background noise which has a level of 5 mV rms. Determine the signalto-noise ratio and the information rate of the digitized signal.
Unpolarized light is incident on three polarizers: The first making an angle of 0 degrees with the vertical; the second making an angle of degrees with the vertical; and the last one making an angle of 90 degrees with the vertical.
CONFUSING, but I know if two charges are the same and opposite they cancel. So, all charges cancel except for the charge at the top of the inner circle which is +2q.
The paper should include your findings based on case study of alternative energy systems and critically evaluate the functions and effectiveness of the systems.

The company finds it efficient to periodically replace all the bulbs in the building at the same time. After how many ours should all the bulbs be simultaneously replaced to ensure that no more than 20% of bulbs have failed before they are replace..
For the following signal x[n] = ( 1 0 n 4 0 otherwise (a) Compute its spectrum following the definition of the Fourier transform. (b) Obtain its magnitude spectrum in one period . Note: pay attention to that the magnitude must be positive.
Derive a state diagram for a Finite State Machine(FSM) that has an input w and an output z. The machine has to generate z = 1 when the privious four values of w were 1001 or 1111; otherwise, z = 0. Overlapping input patterns are allowed.
