The following sections look at three types of time and frequency radio signals that distribute UTC—high frequency (HF), low frequency (LF), and GPS satellite signals.

For each frequency, the expression tells how much of this frequency is contained in the original signal x. The second equation in each case has the original signal x on the left-hand-side, and …

The frequency ν in the SI system is measured in reciprocal seconds s− 1 which is called a Hertz and represented by Hz. Often in Chemistry one will use the reciprocal of the wavelength in …

For a 10KHz sinusoidal input, the gain is 0dB (1) and the phase shift is 0°. For a 10MHz sinusoidal input, the gain is -32dB (0.025), and the phase shift is -176°.

The quantity 2fcutoff is called the Nyquist rate, and the Nyquist criterion says that we must sample faster than the Nyquist rate; i.e., twice the cutoff frequency, in order to approximate X(f).

Given a graph, find the period (wavelength) and frequency. Graph waves of the form y = sin(Bx). B 3 Period (wavelength) is the x-distance between consecutive peaks of the wave graph. 2 …

FREQUENCY escribed as the frequency of the wave. One wave—or cycle—per second is called a Hertz (Hz), after Heinrich Hertz who es blished the existence of radio waves. A wave with …
