Video Modulator for FM/AM-Audio Features FM- and AM-audio modulator Audio carrier output for suppression of harmonics Sync level clamping of video input signal Controlling of peak white value Continuous adjustment of modulation depth for positive or negative values Symmetrical mixer ...
Page 2
For optimal residual carrier suppression, the symmetrical mixer outputs at pins 15, 17 should be connected to a matched balanced-to-unbalanced broadband transformer, e.g. a Guanella transformer with good phase precision at 0 and 180 loss should be less than 3 ...
