RFTYT Lowhpass Filter Used For Transmitters, Receivers, ETC
Low-pass filters are used to transparently pass high frequency signals while blocking or attenuating frequency components above a specific cutoff frequency.
The low-pass filter has high permeability below the cut-off frequency, that is, signals passing below that frequency will be virtually unaffected. Signals above the cut-off frequency are attenuated or blocked by the filter.

RFTYT Highpass Filter Stopband Suppression
High-pass filters are used to pass low-frequency signals transparently while blocking or attenuating frequency components below a specific cutoff frequency.
High-pass filter has a cutoff frequency, also known as a cutoff threshold. This refers to the frequency at which the filter begins to attenuate the low-frequency signal. For example, a 10MHz high-pass filter will block frequency components below 10MHz.

RFTYT Bandstop Filter Q Factor Frequency Range
Band-stop filters have the ability to block or attenuate signals in a specific frequency range, while signals outside that range remain transparent through.
Band-stop filters have two cutoff frequencies, a low cutoff frequency and a high cutoff frequency, forming a frequency range called the “passband”. Signals in the passband range will be largely unaffected by the filter. Band-stop filters form one or more frequency ranges called “stopbands” outside the passband range. The signal in the stopband range is attenuated or completely blocked by the filter.
