  • Patent number: 4788590
    Abstract: An RF converter includes a video modulator and a sound modulator. A modulated video signal from the video modulator and a modulated sound signal from the video modulator are mixed and conducted to a surface acoustic wave (SAW) filter constituted as a band pass filter, an RF television signal being the output of this surface acoustic wave filter. A high frequency side of the amplitude characteristic in the pass band of the surface acoustic wave filter is enhanced in comparison with a low frequency side thereof.

  • Patent number: 4307356
    Abstract: A surface acoustic wave device includes a piezoelectric substrate and a transmitting, a receiving and a reflecting transducer disposed thereon in a row along a predetermined path. The transmitting transducer is responsive to an input signal having a predetermined center frequency for propagating a first surface acoustic wave along the predetermined path. The receiving transducer is located at a location spaced a predetermined distance from the transmitting transducer and is adapted to convert the first acoustic wave to an electrical output signal, but also generates an undesired reflected wave. The reflecting transducer is provided close to one of the other two above-described transducers and is responsive to the first surface acoustic wave to generate a cancellation reflected wave which cancels the undesired reflected wave.

  • Patent number: 4297660
    Abstract: A surface acoustic wave device comprises an input and output transducers. A signal is supplied from a signal input circuit to the input transducer and a surface wave corresponding to the input signal is propagated from the input transducer to the output transducer, from which an electrical signal corresponding to the surface wave is withdrawn and is applied to a signal output circuit. An impedance converting circuit is inserted in series between the signal input circuit and the input transducer and/or between the output transducer and the signal output circuit. It has been discovered that this arrangement reduces the electrical triple transit echo.
