Consider an amateur radio operator transmitting at frequencies in the 20 meters (14-14.3 MHz), 15 meter (21.0-21.45 MHz) or 10 meter (28.0-29.7 MHz) amateur bands using a lowpass filter with 1 dB attenuation at 30 MHz. What is the minimum filter required to attain 30 dB harmonic suppression in any of the low VHF TV channels (54-88 MHz)? (Note, there are amateur bands in the lower HF region, but it is typically the upper HF bands that cause issues)
Consider...
