line frequency การใช้

• The pilot tone frequency is 3.5 times line frequency ( 54687.5 Hz ).
• For G = 10, the CLK line frequency and Root Frequency are equal.
• Maybe the 60hz . line frequency causing the filament to vibrate?
• The AC voltage is the line frequency of the mains.
• Line frequency ) the effect can be safely ignored.
• This is easily determined by doubling the line frequency.
• The line frequency was 11025 Hz with vision broadcast at 46.0 MHz and sound at 42.0 MHz.
• It goes at exactly line frequency, as I recall, but it syncs on the signal, not the line.
• A simple example is the light of a conventional light bulb being modulated at twice the line frequency.
• The difference between the two types is that the synchronous motor rotates in exact synchronism with the line frequency.
• The dot gain, hence the screen angle and line frequency, of a spot color vary according to its intended purpose.
• By contrast, the induction motor requires " " power line frequency, which is carefully controlled in large interconnected grid systems.
• Line frequency flicker in light is detrimental to high speed cameras used in sports event broadcasting for slow motion replays.
• Inputs to the program are line frequency of the Ronchi grating, focal length and diameter of the mirror, and the figure required.
• Whereas SCIMs cannot turn a shaft faster than allowed by the power line frequency, universal motors can run at much higher speeds.
• A filter of this sort is designed for use at a particular frequency, generally fixed by the AC line frequency and rectifier configuration.
• Because of the large inductors and capacitors that must be used, reactive ballasts operated at line frequency tend to be large and heavy.
• The effect is to average out the alternating pull of the magnetic field and so prevent the core from buzzing at twice line frequency.
• Although the level of PD heating is generally low for DC and power line frequencies, it can accelerate failures within high voltage high-frequency equipment.
• Some older computers generated periodic interrupts from the power line frequency because it was controlled by the utilities to eliminate long-term drift of electric clocks.
