Intermediate Frequency. Wireless receivers normally convert the incoming RF signal to a lower intermediate frequency for amplification and final filtering prior to demodulation.

A measurement of the frequency range that can be handled by a specific piece of electrical equipment or loudspeaker when referenced to amplitude. A graph of all the frequencies plotted versus level is the Frequency Response Curve of a particular piece of equipment.

In wireless applications, the accuracy to which the operating frequency is maintained over time and in the presence of environmental changes.

A circuit to generate a stable and precise RF output on any one of a number of preset (or programmable) frequencies. Synthesizers are used as the local oscillators for receivers, and to set the output frequency of transmitters.

In receivers, the process of converting the desired RF frequency results in an undesired sensitivity at a second RF frequency, which is referred to as the image frequency. RF filtering in the receiver is relied upon to reduce to acceptable levels the receiver's susceptibility to spurious RF signals at the image frequency.

In general terms, "frequency" is the rate (how often) at which something repeats. In acoustic terms, it is the rate at which sound Wavesrepeat over time. The greater the number of repeats, the higher the frequency. And the higher the frequency, the higher the pitch of the tone that is produced.

Signals in the human audio range: nominally 20Hz to 20kHz.

Hi All,

Here is the link for the latest free video. This one covers ideas for splitting individual sounds into separate frequency bands. There are also a couple of free racks to download this time.

I'm sorry if this has been answered before but I could not find it searching the site or with google.

i thought some people might find this frequency chart usefull for arranging and e.q'ing.
i printed one out and have it near my mixer for referrence.
