The modulation depth " m " is a convenient experimental parameter when assessing the total harmonic distortion in the demodulated signal.
42.
Until recently, it was not possible to achieve high levels at frequencies down to 20 Hz without high levels of harmonic distortion.
43.
The maximum SPL the microphone can accept is measured for particular values of total harmonic distortion ( THD ), typically 0.5 %.
44.
A further bonus was that third harmonic distortion was much reduced relative to a comparable pentode ( Terman pp 198 9 ).
45.
Output transformers are not perfect devices and will always introduce some odd harmonic distortion and amplitude variation with frequency to the output signal.
46.
This mainly harmonic distortion is a unique pattern of simple and monotonically decaying series of harmonics, dominated by modest levels of second harmonic.
47.
The basic LCC configuration uses a three-phase harmonic distortion is produced at both the DC and AC terminals when this arrangement is used.
48.
The sensitivity is measured at 1 watt to minimize nonlinear effects such as power compression and harmonic distortion, and averaged over the usable bandwidth.
49.
When operating in the linear range, no harmonic distortion or intermodulation distortion ) would occur ( although random noise may still be introduced ).
50.
Conversely, a system that changes the shape of the wave ( beyond simple scaling or shifting ) creates additional harmonics ( harmonic distortion ).
