Product Info

Designed for use in digitization of high definition television signals. These miniature lowpass filters are ideal for suppressing aliasing components in analog and digital HDTV systems. All new HDTV products that require control of delay and amplitude to SMPTE 260M and 274M specifications can be improved by using these filters. The HDTV series filters are amplitude and group delay equalized to reduce ringing in high performance video applications.
