... In order to recover the carrier from the DSB-modulated, a band-pass filter is needed which filters out the upper and lower sideband. As the sidebands can lie in very close proximity to the carrier in broadband signals, this filter must have cutoff edges which are as steep as possible. A downstream p ...

Superheterodyne receiver



In electronics, a superheterodyne receiver (often shortened to superhet) uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original radio carrier frequency. It was invented by US engineer Edwin Armstrong in 1918 during World War I. Virtually all modern radio receivers use the superheterodyne principle. At the cost of an extra frequency converter stage, the superheterodyne receiver provides superior selectivity and sensitivity compared with simpler designs.
