Patent abstract
A multi-channel tuner apparatus is provided which is capable of simultaneously and independently selecting a plurality of channels for reception. The apparatus comprises a plurality of tuners, each of which converts a selected channel to a near-zero intermediate frequency. The output signals from the tuners are supplied to respective sample/hold circuits, whose outputs are supplied to a single analogue/digital converter for multiplexing the tuner signals and converting them to the digital domain. A common demodulator arrangement processes the digital domain signal to extract the information from all of the selected channels.
