Answer is:
antenna
Explanation:
AM produced by a square law device is passed through a power amplifier and fed to antenna
Answer is:
recovering the modulating signal from the received signal
Explanation:
The?detection?of?AM?radio signals is a diode application. The modulated?AM?carrier wave is received by the antenna of the radio receiver and is rectified
Answer is:
diodes for rectification and capacitors for storing the peaks
Explanation:
The?detection?of?AM?radio signals is a diode application. The modulated?AM?carrier wave is received by the antenna of the radio receiver and is rectified
Answer is:
10 MHz
Explanation:
Frequencies?below approximately 10?MHz (wavelengths longer than 30 meters), including broadcasts in the?mediumwave?and?shortwave?bands (and to some extent?longwave), propagate most efficiently by skywave at night. Frequencies above 10?MHz (wavelengths shorter than 30 meters) typically propagate most efficiently during the day. Frequencies lower than 3?kHz have a wavelength longer than the distance between the Earth and the ionosphere. The?maximum usable frequency?for skywave propagation is strongly influenced by?sunspot?number.
