Textbook Question
Chapter 6, Problem 6.1P
What is the fundamental concept of Fourier theory?
Expert Solution & Answer
To determine
To discuss: The fundamental concept of the Fourier theory.
Explanation of Solution
According to the Fundamental concept of the Fourier theory, all signals are the summation of the different sinusoidal signal which are of the different amplitude, frequencies and the phase.
The representation of the signal:
Referring to the above diagram, the signal 4 is the sum of the signal 2 and signal 3.
Whereas the signal 2 and signal 3 are the sinusoidal signal of the different amplitude and the different frequency.
Therefore, the signal 4 is the example of the Fourier theory.

The former expert solved the question, but I didn't
understand how he simplified the fractions.
A communication satellite is in stationary (synchronous) orbit about the carch (assume
altitude of 22.300 statute miles). Its transmitter generates 8.0 W. Assume the transmit-
ting antenna is isotropic. Its signal is received by the 210-ft diameter tracking parabo-
loidal antenna on the earth at the NASA tracking station at Goldstone, California. Also
assume no resistive loss in either antenna, perfect polarization match, and perfect
impedance match at both antennas. At a frequency of 2 GHz, determine the:
(a) power density (in watts/m²) incident on the receiving antenna.
(b) power received by the ground-based antenna whose gain is 60 dB.
