Question B-008-005-001

What type of filter might be connected to an amateur HF transmitter to cut down on harmonic radiation?

Correct Answer

A low pass filter

Explanation

A low-pass filter placed after the transmitter allows the desired HF fundamental frequency (~1-30 MHz) to pass but attenuates higher frequencies, including harmonics (which start at 2x the fundamental).
