Same as a FILAMENT .
A radar that provides target altitude, range, and bearing data .
A building at a transmitter site that contains antenna loading, coupling, and tuning circuits .
The electromagnetic unit of inductance or mutual inductance. The inductance of a circuit is 1 henry when a current variation of 1 ampere per second induces 1 volt. In electronics, smaller units are used, such as the millihenry (mH), which is one-thousandth of a henry (H), and the microhenry (μH) which is one-millionth of a henry .
A unit of frequency equal to one cycle per second .
A half-wave antenna that is installed some distance above ground and positioned either vertically or horizontally .
The use of an a.f. voltage to distinguish between available signals. The
incoming cw signal is mixed with locally generated oscillations to give an a.f. output .
(1) The process of mixing two frequencies across a nonlinear impedance . (2) The process of mixing the incoming signal with the local oscillator frequency. This produces the two fundamentals and the sum and difference frequencies .
Same as SEXADECIMAL. A number system with a base of sixteen; also pertains to
conditions, choices, or selections that have sixteen possible values or states .
