Dc power supply with their basic parts.

Rectifier - converts sine wave input to pulsating DC output
Filter - smoothen the output of the waveform/reduce fluctuations
Regulator- provides constant/dc voltage and also maintains the output voltage at any load.
Load- recipient of the voltage

So, the answer is filter not a regulator.

You are right @Zeeshan Zamir.

Regulator for only regulated purposes. Filter doing the unwanted pulses from rectifier circuits.

The filter is used for filtering purposes. Even after filtering that the signal contains some distortion. So, regulators is used to make a DC output smooth.

I think it is oscillator.

Transformer generates higher voltage with out any change in frequency. Rectifier converts half of the AC into DC. Filters are used to remove unwanted material.

I think Filter is the answer.

Filter is the right answer.

As per my knowledge, filter is the right answer because after regulated voltage some ac component present in that remove with filter section only.

Regulator (sewer) , a control device used in a combined sewer system and The devices which converts the pulsating DC into pure DC is called filter so this is simple to us the answer is filter.

Regulator is a circuit that maintains a constant dc voltage filter eliminates the fluctuations in the rectified voltage & produced relatively smooth dc voltage.
