  • In-band-on-channel broadcast system for digital data
    Patent number: 7388911
    Abstract: An FM broadcast transmitter transmits a broadcast signal having a carrier at a broadcast frequency and sidebands, able to be transmitted at full power, within a transmission bandwidth around the carrier. It includes a source of a modulated FM stereo signal having a carrier at the broadcast frequency and having sidebands with a bandwidth less than the transmission bandwidth representing a stereo signal. It also includes a source of a modulated in-band-on-channel (IBOC) signal, having carrier pulses spaced relative to each other to represent the IBOC digital data signal encoded as a variable pulse width encoded signal, and a bandwidth within the transmission bandwidth not overlapping the FM stereo signal sidebands. A signal combiner combines the modulated FM stereo signal and the modulated IBOC signal to form the broadcast signal.

  • Two band 25 channel cordless telephone system
    Patent number: 5722079
    Abstract: A cordless telephone system divides the 25 channel bandwidth allocated by the Federal Communications Commission (FCC) into two bands in order to obtain improved noise performance. The front end is tuned to the center frequency of each band and the tuning of the receiver to specific channel frequencies is accomplished via a PLL.
