A bandpass filter is an electronic device or circuit that allows signals between two particular frequencies to pass, but that discriminates against signals at other frequencies.Bandpass filters are used primarily in wireless transmitters and receivers.
balanced modulator mixes the audio signal and the radio frequency carrier, but suppresses the carrier, leaving only the sidebands. The output from the balanced modulator is a double sideband suppressed carrier signal and it contains all the information that the AM signal has, but without the carrier.
