... To satisfy Nyquist sampling criterion, need to sample at more than 40kHz. Sampling at around 40 kHz would mean that all energy above 20Hz must be filtered out without affecting the sound in the range 20-20kHz. This would require a very sharp anti-aliassing filter. Hence the sampling frequency is mad ...

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.
