...  Delay distortion: occurs in guided media. It is caused by the fact that the velocity of propagation of a signal through a cable is different for different frequencies. For a signal with a given bandwidth, the velocity tends to be highest near the center frequency of the signal and to fall off towa ...

... 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.
