These point-contact diodes were used to rectify signals, and make simple AM radio receivers (crystal radios). However, it took many years before the three terminal solid state device - the transistor - was discovered. The transistor was invented in 1947 by three American physicists at the ...
Even though many components of the receiver shown are implemented in chip form (low-power and miniaturized receivers practically come as single chips), a discrete layout of a receiver allowed us to study the superheterodyne principle, demodulation, and automatic gain control. It should be pointed ...
Transistors also play an important role in amplifying electronic signals. For example, in radio applications such as FM receivers, where the received electrical signal is weak due to disturbances, amplification provides audible output. Transistors increase signal strength to provide this amplification. ...
