Homework Statement
A continuous-time system has the input/output relationship
y(t) = \int_{-\infty}^{t} (t - \lambda + 2)x(\lambda) d\lambda
Determine the impulse response h(t) of the system

Convolution theorems
y(t) = x(t) * h(t)
Where y(t) is the output...
I want to find the Fourier coefficients for the following signal:
\cos(2 \pi t)^2
Can I simply use the identity?:
\frac{1}{2} + \frac{\cos(2 \pi t)}{2}
And then use the complex definition:
\frac{1}{2} + \frac{1}{4} (\exp{j2 \pi t} + \exp{-j2 \pi t}) From the synthesis equation I can...
This question deals with an example found in Signals and Systems, 2ed, page 99, ex 2.7. But I can summarize it here:
EDIT - my latex doesn't seem to work ...
x(t) = (1, 0 < t < T) or (0, otherwise)
h(t) = (t, 0 < t < 2T) or (0, otherwise)
I realize there are five bounds...
I know that CT Scans provide still images of various parts of the whole human body.
I also know that Ultrasound provides live images and movements of fetuses.
Is there a machine/scanner that scans the body and provides real-time video of the organs in operation, including blood-flowing, heart...
The following CT scan of Terri Schiavo purportedly suggests that her cerebral cortex consisted entirely of fluid at the time the image was made many years ago.

I'm skeptical of the claim because the image is too symmetrical. An injury...

Good afternoon,
I have some formulas to calculate ( aprox in most cases ) the diference between UTC ( CT ) and TDB. There are periods that already have a full coverage from the astronomers ( like the period 1600/1620 to ~2000 ).
Still, two problems remain:
1) The calculation of a specific...

If you do a google on critical thinking you will find 5 million Web sites. You will also discover the massive effort being made by education to teach Critical Thinking in our schools.
The best of these 5 million sites is said to be contained at...
