practice the condenser is also adjustable so as to increase the range of wave length.
When the two circuits are adjusted to harmonize with the received waves, an electrical pressure is created in the condenser, which pressure can be detected and made manifest by suitable apparatus. This part of the system is called a detector.
15. Detectors
The function of the detector is to respond to, and make manifest in some manner, the electric oscillations set up
