One card was installed in rackmount PC in the Federal headend, another in the El Cajon headend . 1500 high pass filters were installed to eliminate any ingress from the drops.
12.
A first-order low or high pass filter has a standard response curve which reduces the unwanted frequencies well above or below the cutoff frequency with a slope of 6 dB per octave.
13.
Unlike ABR settings, the high pass filter might be approximately 40 to 90 Hz and low pass filter might be between 320 and 720 Hz with typical filter slopes of 6 dB per octave.
14.
The high pass filter can either be applied after the low pass filters, or before ( if applied before the low pass filters, the high pass filter only affects an external audio signal ).
15.
The high pass filter can either be applied after the low pass filters, or before ( if applied before the low pass filters, the high pass filter only affects an external audio signal ).
16.
A " 70cm signal path " goes through a high pass filter network, through the RF directional coupler / power detector ( not on rx ) to a low pass filter to a PIN-diode.
17.
Depending on the application, this may require one or more of the following : a simple proportion ( gain or attenuation ), an integral ( low pass filter ) and / or derivative ( high pass filter ).
18.
The " Intermediate Transform " section allows adjustment of brightness, tint, hue, saturation, bilevel ( high pass filter ) or profile assignment, to either grayscale, RGB or CMYK, or all data in the file.
19.
In that situation, the diplexer consists of a lowpass filter connecting ports L and S and high pass filter connecting ports H and S . Ideally, all the lowband signal power on port L is transferred to the S port and vice versa.
20.
The radio frequency ( RF ) signal from the tuned circuit ( bandpass filter ) is amplified, then passes through the high pass filter to the demodulator, which extracts the audio frequency ( AF ) ( modulation ) signal from the carrier wave.
