Center Frequency
In electrical engineering and telecommunications , the CENTER FREQUENCY of a filter or channel is a measure of a central frequency between the upper and lower cutoff frequencies . It is usually defined as either the arithmetic mean or the geometric mean of the lower cutoff frequency and the upper cutoff frequency of a band-pass system or a band-stop system . Typically, the geometric mean is used in systems based on certain transformations of lowpass filter designs, where the frequency response is constructed to be symmetric on a logarithmic frequency scale. The geometric center frequency corresponds to a mapping of the DC response of the prototype lowpass filter, which is a resonant frequency sometimes equal to the peak frequency of such systems, for example as in a Butterworth filter

Call Sign
In broadcasting and radio communications , a CALL SIGN (also known as a CALL NAME or CALL LETTERS—and historically as a CALL SIGNAL—or abbreviated as a CALL) is a unique designation for a transmitter station . In North America, they are used for all FCC licensed transmitters. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations , there needed to be a way to address each one when sending a telegram . In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations aboard ships at sea
