tussenfrequentiefilter
A tussenfrequentiefilter, often translated as intermediate frequency filter or IF filter, is a crucial component in superheterodyne radio receivers. Its primary function is to select a specific range of frequencies from the incoming radio signal while rejecting others. In a superheterodyne receiver, the incoming radio frequency signal is mixed with a local oscillator frequency to produce an intermediate frequency (IF). This IF is standardized and typically much lower than the original radio frequency. The tussenfrequentiefilter is placed after the mixer and before the detector.
The filter's bandwidth is designed to precisely match the bandwidth of the desired transmission channel. This
Various filter technologies can be employed for the tussenfrequentiefilter, including LC filters, crystal filters, and ceramic
