At top right is a sectional excerpt showing the Wink (INK) Vortac, and the frequency box, which lists 122.05 as a discrete frequency
for contacting San Angelo Flight Service in the area around INK.
Data collected in the frequency domain is not continuous, but a finite number of discrete frequency
To this end, the sounds of three arc, gas metal arc and spot weld machines were transferred to a computer during welding process via a microphone and recorded separately and then, by applying FFT, discrete frequency
components were ascertained.
For each of the look angles, frequency-diverse backscattered electric field was gathered for the stepped frequencies ranging from 1 to 8 GHz for the total of 100 discrete frequency
Use of discrete frequency
tone in audible spectra," Applied Acoustics, vol.
I switched to UHF and contacted them on the discrete frequency
we had discussed.
Ideal phase and amplitude relations based on analysis in (4)-(11) for these initial parameters and discrete frequency
are given in Fig.
For the experiment in this paper, we measure the received energy across a 23-element array at each discrete frequency
, across a stepped frequency ramp of bandwidth BW, at a frequency step interval of [DELTA]f.
where [X.sub.t](n) means the logarithmic magnitude of discrete Fourier transform of the fth frame, and [Q.sub.k] is the number of elements in a subset of the discrete frequency
space for each pitch class .
The use allocated to a discrete frequency
band is called a service.
The frequency domain method indirectly obtains the time domain response through transmitting a discrete frequency
signal at the transmission terminal, from which an identical signal is introduced into the reception terminal as a reference signal, and through comparing it with the reception signal and analyzing the plural frequency domain response of a channel.
Testing order (sweep vs discrete frequency
and continuous vs pulsed tones) was randomized and counterbalanced.
