  This paper considers the recovery of continuous signals in infinite
dimensional spaces from the magnitude of their frequency samples. It proposes a
sampling scheme which involves a combination of oversampling and modulations
with complex exponentials. Sufficient conditions are given such that almost
every signal with compact support can be reconstructed up to a unimodular
constant using only its magnitude samples in the frequency domain. Finally it
is shown that an average sampling rate of four times the Nyquist rate is enough
to reconstruct almost every time-limited signal.
