The frequency of an FM broadcast station ( more strictly its assigned nominal center frequency ) is usually an exact multiple of 100 kHz.
22.
The term load-pull derives from classical oscillator characterization whereupon variation of the load impedance pulls the oscillation center frequency away from nominal.
23.
The electrical conductivity of the ground, the transmitted center frequency, and the radiated power all may limit the effective depth range of GPR investigation.
24.
They illustrate the level of a masker ( dB SPL ) tone at threshold, as a function of deviation from center frequency ( Hz ).
25.
The difference is that receivers also down-convert the subbands to a low center frequency that can be re-sampled at a reduced rate.
26.
In RADSL, the baud rate, center frequency, and constellation size of the downstream and upstream channels can be adjusted while the connection is in operation.
27.
At no time may any transmission exceed the channel bandwidth of 2.8 kHz and the center of all CW emissions must coincide with the authorized center frequencies.
28.
Then, the single-sideband complex signal centered at zero is upconverted to a real signal, by another pair of quadrature mixers, to the desired center frequency.
29.
In North America, UHF can be used unlicensed for 902 928 MHz ( ?3 MHz from the 915 MHz center frequency ), but restrictions exist for transmission power.
30.
HD Radio signals on AM, however, use more bandwidth signal wise and often create " hash " on surrounding frequencies, up to 30 kHz from the center frequency.
