The number of complaints will go up with the setting up filter centers
and a mechanism will be evolved to deal with them in a befitting manner.
In October 1943, the GOC and the filter centers
were taken off 24-hour basis and put into reserve, being activated after that only occasionally for tests and training, and completely deactivated on the continent in 1944 (I believe they continued on the Hawaiian islands until V-J Day).
5% shift upwards in the dielectric constant will result in approximately 60 MHz downwards shift in the filter center
It is shown that parameters a and d control the filter center
frequency and bandwidth and that parameter e dominantly affects the filter 3dB bandwidth.
To simplify the model, the IF filter center
frequency is set to zero.
Recent investigations have examined combining the two methods at one point in the mold by inserting inoculating pellets in the filter centers
