 +<WRAP centeralign>**Abstract**</WRAP>
 +We propose an unbiased measure of ex-post price variation in the
 +frequency domain. It is periodogram-based. When intraday prices are
 +contaminated by market microstructure noise, the proposed estimator
 +behaves like a filter: it removes the noise by filtering out high
 +frequency periodograms. In other words, the proposed estimator converts
 +the high frequency data into low frequency periodograms. We show, via a
 +simulation study and an application to Microsoft transaction prices, that
 +the proposed estimator is insensitive to the choice of sampling frequency
 +and it is competitive with other existing noise-corrected volatility
 +measures.
