And that'll actually build up the intuition on what the frequency domain is all about.

His business took him there quite often.

Interesting things happen when you go down in the bandwidth, when they start to differ.

Or how do you go from the frequency domain to the time domain?

Approximately 680,000 121.5 MHz and 376,000 406 MHz emergency beacons are currently in use worldwide.

This is frequency.

Why do you stammer?

Operating on the internationally recognized aviation distress frequency, 121.5 MHz beacons provide a significant alerting service worldwide for commercial and general aviation.

And you can see on this figure, that the frequency range and the decibel range, the dynamic range of music is far more heterogeneous.

So they are inverses of each other.

Number two hesitation is bad.

The length of a string, L, varies inversely as the frequency.

I've got a frequency counter right here.

Now, so I know the frequency.

Hesitation now may destroy us.

Getting to feel free and easy.

To monitor a VLF signal, a radio receiver is needed that can tune to VLF stations, together with an antenna to pick up the VLF signals and a computer to keep track of the data.

The most popular design for radio applications was torsional resonators because radio IF typically lies in the 100 to 500 kHz band.

A low frequency wave doesn't have nearly as much umph as a high frequency one.

In this case, the frequency is lower.
