Notes

1. Low-ohmic preferred, otherwise the signal loss and spreading at COMP, caused by Z_Oand the composite input

impedance (see Chapter “Characteristics”; row head “Input level adjustment control”) must be taken into account.

2. In order to prevent clipping at over-modulation (maximum deviation in the BTSC system for 100% modulation is

73 kHz).

3. For example colour bar or flat field white; 100% video modulation.
