Using a direct sequence spread spectrum (DSSS) technique spreads a narrow band channel so that it occupies greater frequency spectrum.  By doing this, the signal has greater immunity from narrow band noise. 

A signal has a frequency range from 30MHz to 100,000 kHz.  What is the frequency bandwidth?

Determine the data rate possible given 64-QAM modulation where M=64, and baud rate is 4800 baud.

1,000,000 Hz (1E6) is equivalent to:

Given the following parameters, determine the correct sinusoidal equation for:  f=3kHz, A=10v, φ (phase angle)=+π/4 radians. 

The period of a carrier wave is T=3E-6 seconds.  Determine the frequency and wavelength of the carrier wave.

Analog virtual circuits enable several analog users to share a common physical link.

By viewing a signal in the frequency domain, you can determine the amplitude, signal frequency and frequency bandwidth of the signal.

What was it known as when Roosevelt tried to alter the judicial system and the courts in his favor by expanding the number of justices and adding new ones who supported his views?

Which of the following ran against Herbert Hoover in the 1932 election, came from a wealthy background, was governor of New York, and stricken with polio at a young age?
