A) Whole number multiples of a frequency. F x 1 is called the fundamental or first harmonic; F x 2 is the second harmonic; F x 3 is the third harmonic; etc. b) Integral multiples of a fundamental frequency are harmonics of that frequency. A pure sine wave is free of harmonics.
Adding harmonics to a fundamental frequency will change its wave shape.
A square wave contains a fundamental frequency plus all the odd harmonics of that frequency.
Industry:Software
In a magnetic recorder, the generally ring-shaped electromagnet across which the tape is drawn. Depending on its function, it either erases a previous recoding, converts an electrical signal to a corresponding magnetic pattern and records it on the tape, or picks up a magnetic pattern already on the tape and converts it to an electrical playback signal.
2-Head: The system used on most cassette recorders, requiring that playback occur after the recording has been made. 3-Head: Refers to the recording/playback head configuration within the recorder. A 3-head system allows simultaneous playback of recorded material.
Industry:Software
Mechanical adjustment of the spatial relationships between the head gaps and the tape.
Industry:Software
An assembly holding an erase, record, and playback head in a certain physical alignment.
Industry:Software
A device used to neutralise possible residual or induced magnetism in heads or tape guides.
Industry:Software
Facility in cable system from which all signals originate. Local and distant television stations, and satellite programming, are picked up and amplified for re-transmission through system.
Industry:Software
A block of data in the coded bit stream containing the coded representation of a number of data elements pertaining to the coded data that follow the header in the bit stream.
Industry:Software
A) The number of dB increases possible above the operation level (0 VU) before unacceptable distortion occurs.
b) In composition, the space between a subject’s head and the upper boundary of the frame.
c) The difference between the nominal level (average) and the maximum operating level (just prior to “unacceptable” distortion) in any system or device. Because it is a pure ratio, there is no unit or reference-level qualifier associated with headroom: simply “dB”; headroom expressed in dB accurately refers to both voltage and power.
Industry:Software
A way of winding tape so that the beginning of a selection is on the outside of the reel.
