PHYS 536 Active Filters Introduction The Low Pass
... Better filter performance can be obtained by including more R-C attenuators. (Each RC attenuator contributes one “pole” to the filter.) Only two RC attenuators can be used with one op-amp, hence better filters have several op amps in series. For example, an 8-pole filter would use 4 op amps. The individ ...

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.
