1. Consider the following signal:
x (t) = cos 2000лt + 2 соs 4000лt.
What would this signal look like on a spectrum analyzer. Be sure to
indicate relative magnitudes and frequencies. Describe the spectrum in
words, e.g., "spikes at ..."
If this signal were multiplied by a 1 MHz sine wave, find the spectrum of
the product. (Describe in words.)
The spectrum of a typical star shows absorption lines at different wavelengths than their laboratory values. If the observed wavelength is
greater than its laboratory value of 656.3 nm, one can conclude that ...
A. The separation between Earth and the star is decreasing.
B. The separation between Earth and the star is increasing.
O C. The separation between Earth and the star is unchanging
D. No conclusion is possible.
Hubble’s Field of View. Large telescopes often have small fields of view. For example, the Hubble Space Telescope’s (HST’s) advanced camera has a field of view that is roughly square and about 0.06° on a side.
a. Calculate the angular area of the HST’s field of view in square degrees.
b. The angular area of the entire sky is about 41,250 square degrees. How many pictures would the HST have to take with its camera to obtain a complete picture of the entire sky?
