1. All specifications subject to change without notice.
2. Unless otherwise noted, T
3. 100% EIM (Equivalent Input Modulation) is that level which would cause 100% modulation of the L–R subcarrier if
4. Response is given in deviation from the theoretical ideal curves for dbx-TV (BTSC) compression/expansion.
the 525CH were replaced with a 75- sec preemphasis network. See the EIA’s BTSC Recommended Practices for
