An electronic circuit whose output has a frequency that is a multiple of the frequency of the input signal. Frequency doublers and triplers are commonly used frequency multipliers.
Industry:Aviation
An electronic circuit whose output has a frequency that is an exact divisor of the frequency at the input. If a signal of 100 kilohertz is placed on the input of a frequency divider that divides by two, the frequency at the output will be 50 kilohertz.
Industry:Aviation
An electronic circuit whose output is determined by the sum of all of its inputs.
Industry:Aviation
An electronic circuit whose output is proportional to the rate of change of the signal in the input circuit.
Industry:Aviation
An electronic circuit whose output is resonant at the second harmonic of the input signal. The frequency of the second harmonic of an alternating current is exactly two times the frequency of the input AC. The output frequency of the frequency doubler is two times that of the input.
Industry:Aviation
An electronic circuit within a radio receiver that keeps the output volume relatively constant, even though the strength of the signal picked up by the receiver changes.
Industry:Aviation
An electronic component that controls the flow of electrons without the use of any heated filaments, vacuum spaces, or moving parts. Semiconductor devices such as diodes, transistors, and silicon controlled rectifiers are examples of solid-state devices.
Industry:Aviation
An electronic computer consisting of a central processing unit (CPU), input and output devices, and some memory capacity. Microcomputers are smaller and slower than either mini-computers or mainframe computers.
Industry:Aviation
An electronic computer in an aircraft that senses pitot pressure, static pressure, and total air temperature. It produces an indication of altitude, indicated airspeed, true airspeed, and Mach number. The output of the ADC is usable by any of the engine or flight control computers.
Industry:Aviation
An electronic computer which operates by converting different levels of voltage or current into numerical values in the decimal number system. One level of voltage (or current) represents the number one, another level represents two, and so on. Adding or subtracting the voltages (or currents) which are analogs of the numbers produces a voltage (or current) which is the electrical equivalent of the sum or the difference of the numbers.
There are also mechanical analog computers that combine mechanical analogs of numbers to solve mathematical problems.
