Consider the casual LTI system where the output relates to the input by the following differential equation:
dy(t)/dt + 2y(t) = x(t)
a) Determine the frequency response H(jw).
b) Determine Y(jw) and y(t) if you have inputs with the following Fourier Transforms:
a. X(jw)=(1+jw)/(2+jw)
b. X(jw)=(2+jw)/(1+jw)
c. X(jw)=1/(1+jw)(2+jw)
An infinitely long line charge (Pl= 21 PI nC/m) lies along the Z-axis. An infinte area sheet charge PS= 3nC/m^2 lies in the X-Z plane at a distance Y =10 m. a) Using Gauss' law find the field E due to the line charge.

When a square wave with a fundamental frequency of 2khz and amplitude 5v and comprised of up to five odd harmonic (each successive odd harmonic having half the amplitude of its predecessor) is passed though a standard telephone line of bandwidth o..
A second method of development will recover only 50% of the ore deposit , but it will cost only $15 per ton of material removed.Subsequent processing of the removed ore recovers 300 pounds of metal from each ton of processed ore and cost $40 per ..
An AM broadcast receiver's pre-selector has a total effective Q of 90 to a received signal at 1180 kHz and uses an IF of 455 kHz. Calculate the image frequency and its dB of suppression.
According to the Merriam-Webster dictionary, an invention is defined as something invented as a product of the imagination such as a device, contrivance, or process originated after study and experiment and an innovation is defined as the introduc..
moore sequential circuit has one input and one output, that creates a pulse when ever its input signal goes from 1 to 0 after this pulse a new pulse will not be given unless the input signal is again returned to 1 and then tranistion back to 0.
