pulsating dc造句

An interrupter more efficient than the doorbell would convert dc to pulsating dc more efficiently.
The pulsating dc voltage is averaged and forwarded through the selector switch to the fuel flow indicator.
This pulsating dc can be stepped up with a transformer to whatever voltage is needed, then changed to dc at that voltage via rectification.
In order to provide the necessary voltage for a radio from the typical 6 or 12 volt DC supply available in a car or from a farm lighting battery, it was necessary to convert the steady DC supply to a pulsating DC and use a transformer to increase the voltage.
Since current can only pass in one direction, such a diode ( or " rectifier " ) will convert alternating current ( AC ) to pulsating DC . Diodes can therefore be used in a DC power supply, as a demodulator of amplitude modulated ( AM ) radio signals and for similar functions.
It's difficult to find pulsating dc in a sentence. 用pulsating dc造句挺难的

The rotary converter is somewhat more complex than this trivial case because it delivers near-DC rather than the pulsating DC that would result from just the reversing switch, but the analogy may be helpful in understanding how the rotary converter avoids transforming all of the energy from electrical to mechanical and back to electrical.
