<p>Provided is a receiving apparatus for processing an analog baseband signal in an information terminal that communicates using a dielectric. The receiving apparatus includes an electrode for receiving an electric-field signal induced in a dielectric; a first gain adjuster for adjusting a gain by amplifying the received signal; a channel selection filter for selecting only a signal corresponding to a receive channel bandwidth from the gain-adjusted signal; a second gain adjuster for adjusting a gain by amplifying the selected signal; a comparator for converting a signal output from the second gain adjuster into a digital signal; an oversampler for oversampling the digital signal at a frequency f Clock higher than a receive channel frequency f Signal; a demodulator for demodulating the oversampled signal; and a clock generator for providing necessary clocks to the oversampler and the demodulator.</p>
