2 ~ 33MHz band-pass filter circuit
Band-pass filter is to pass all frequencies which are higher than for those low-end cutoff frequency and are lower than the high cutoff frequency. The designed band in the shown figure is from ZMHz to 33MHz. therefore, it covers the entire HF shortwave band to eliminate interference from the LF and MWAM band and VHF television broadcasting stations. It should be noted that each part is within its own respective shield. Such is quite a good design for any multiply-section filter because it prevents the mutual influences within the components (especially the coil).
