Description

The 3271 series of deletion filters attenuate the entire channel spectrum from video carrier to aural carrier to allow reinsertion of new information without interference.

The 55 dB (typical) continuous suppression from video carrier to aural carrier has been found more than ample for reinsertion.* Attenuation drops sharply at channel edges to preserve upper and lower adjacent channels. The operating temperature for 3271 Mid/High/Super/Hyper is from 10 degree C to 32 degree C.

All models are AC/DC passing. 1 amp Max.
(All units pass return band 5-48 MHz)

Features:

Special assemblies of several channel deletion filters are available for:

• Suppressing contiguous channel blocks
• Suppressing several non-contiguous channels
• Spectrum splitting “Brickwall” highpass or lowpass filters
• Temperature compensated models available
