Hi, I noticed in several circuits that the 10MHz isolation transformer in input and output circuits have a 6.8nF or 10nF capacitor to GND. How necessary is this for suppression of unwanted signals? Is the transformer itself not sufficient? I would expect common mode issues to be a bit worse with the cap in place.
The circuit I refer to can be seen here: http://www.uploadarchief.net/files/download/cap2gnd.png The first one is an output as described in the Efratom FRK manual, the second one the input in the TADD-2 manual.
