Frequency characteristic - the 19 kHz interferes at
the high end. The de-emphasis capacitors on the outputs have been changed from 15 nF to 12+2,2 nF (=14,4 nF) ![]() |
|
Channel separation. The roll off above 2 kHz is due to the low-pass filter (HP5489A) at the outputs in order to eliminate interference from the 19 kHz. ![]() |
|
Frequency spectrum without modulation. 19 kHz and 57 kHz are quite high and a low pass filter is recommended. ![]() |
