C "'between these frequencies, which was in the audio frequency range.
2.
Thus, valves with low noise at high frequency do not necessarily have low noise in the audio frequency range.
3.
Some radio monitoring hobbyists record ELF pitch, so that it can be brought into the audio frequency range for audibility.
4.
The result is determined by the lowest curve which is not touched by the measured spectrum at any position in the audio frequency range.
5.
An "'audio filter "'is a frequency dependent amplifier circuit, working in the audio frequency range, 0 Hz to beyond 20 kHz.
6.
Such noise signals provide equal energy at each octave of the audio frequency range that the sound system can reproduce, unlike a stimulus signal of music or speech which emphasizes some frequencies over others.
7.
The IBOC system allows transmission of an audio frequency range extending to approximately 15 kHz, 2-ch Stereo on the AM band, but with significant digital artifact and aliasing due to substantial codec inadequacy.
8.
Nevertheless, a 2N3055 ( and many other power transistors originating from this era ) cannot be assumed to have great high-frequency performance and there can be degradation of phase-shift and open-loop gain even within the audio frequency range.
9.
Non-linear filters have many applications, especially in the removal of certain types of audio frequency range; and all digital signal processing depends on non-linear filters ( analog-to-digital converters ) to transform analog signals to binary numbers.
10.
In audio amplifiers, the bandwidth limitations introduced by compensation are still far beyond the audio frequency range, and the slew rate limitations can be configured such that full amplitude 20 kHz signal can be reproduced without the signal encountering slew rate distortion, which is not even necessary for reproducing actual audio material.
