An electronic amplifier in which the current in its output circuit is greater than the current in its input circuit.
Industry:Aviation
An electronic amplifier which can amplify direct-current signals and alternating current signals having a very low frequency.
Industry:Aviation
An electronic amplifier whose output current flows at all times. The output of a class-A amplifier has the same waveform as the input, but the amplitude of the output is greater.
Industry:Aviation
An electronic amplifier whose output current flows only during a small portion of one half of the input cycle. Class-C amplifiers are used to sustain radio-frequency oscillators by supplying pulses of energy to replace the energy lost in the resistance in the circuit.
Industry:Aviation
An electronic amplifier whose output current flows only during one half of the input cycle. Two class-B amplifiers can be connected in such a way that each amplifies one half of the input signal. Both amplifiers are connected to a single output device. Class-B amplifiers are called push-pull amplifiers.
Industry:Aviation
An electronic amplifier with two output circuits. The output signals from these two circuits are equal in amplitude but opposite in phase. A balanced amplifier is also called a push-pull amplifier.
Industry:Aviation
An electronic calculator controlled by a program stored in its memory. A programmable calculator is a versatile instrument that allows the use of different programs to solve many different types of problems.
Industry:Aviation
An electronic circuit capable of increasing voltage. Voltage amplifiers normally supply an extremely small amount of current.
Industry:Aviation
An electronic circuit having a high ratio of circuit impedance to resistance. Q is a measure of the efficiency of a reactive circuit.
Industry:Aviation
An electronic circuit in which a small change in voltage or current at its input controls a much larger change in voltage or current at its output.
