A monitor can support and monitor refresh rate is related to the line frequency.
Since heating power is symmetric for each half cycle of applied voltage, the principle component of this hum is twice the line frequency (and even harmonics of the line frequency).
With increase in defect severity, energy is distributed to the sidebands of the gear mesh frequency across supply line frequency.
The duty factor of line drive pulses is slightly dependent on the actual line frequency.
Typically caused by distortions to the frequency components below the horizontal line frequency.sentence dictionary
Line frequency hum, primarily induced by imbalance in the filament circuit wiring, the transformer used to power the filament, coupling into the signal leads, etc.
When the line frequency is increased, the distortion will become more serious.
