Therefore, unlike the Choi-Williams distribution function, the cone-shape distribution function can effectively reduce the cross-term results form two component with same center frequency.
32.
Each spectrum is sub-divided into " channels " with a center frequency and bandwidth, analogous to the way radio and TV broadcast bands are sub-divided.
33.
The lowest and almost-unused channel, channel 200, extends from 87.8 MHz to 88.0 MHz; thus its center frequency is 87.9 MHz.
34.
Where " f " is the center frequency of the filter in kHz and ERB ( " f " ) is the bandwidth of the filter in Hz.
35.
In 1976, Crown patented the synergistic Q, 1 / 2-octave filters placed on octave centers but with adjustable frequency knobs to shift the center frequency for greater flexibility.
36.
E . g ., a passband filter that has a bandwidth of 2 MHz with center frequency 10 MHz will have a fractional bandwidth of 2 / 10, or 20 %.
37.
The standard is 25 kHz spacing and the center frequency of each channel may be offset in a number of fashions such as ?2.5 kHz or even ?.25 kHz.
38.
Sweep it back and forth over the feedback frequency to find the center frequency by finding the lower and upper frequency of the ring and setting it to the middle between these two frequencies.
39.
Where f _ 0 and \ sigma are the parameters of the filter . f _ 0 will give the center frequency of the filter . \ sigma affects the bandwidth of the filter.
40.
The residual distortion is dependent upon the bandwidth of the tuned load, with the center frequency seeing very little distortion, but greater attenuation the farther from the tuned frequency that the signal gets.
