Electronics (Mike Jaroch)

An antenna that is a wavelength or more long at its operating frequency [10].

Those waves in which the disturbance (back and forth motion) takes place in
the direction of propagation. Sometimes called compression waves [10].

A curved conductor that connects the ends of a coaxial cable or other transmission line and projects into a waveguide or resonant cavity for the purpose of injecting or extracting energy [10] [11].

Inefficient coupling of energy from one circuit to another that is desirable in some applications. Also called weak coupling [11].

The band of frequencies from 30 kHz to 300 kHz [17].

Modulation produced in an earlier stage than the final [12].

See PREAMPLIFIER [18].

A filter that passes a majority of the low frequencies on to the next circuit and
rejects, or attenuates, the higher frequencies. Also called a high-frequency discriminator [9] [12].

All difference frequencies below that of the carrier [12].

The lowest frequency a circuit will pass [9].
