摘要： A circuit for demodulating digital voice signals to prevent generation of large voice distortion when the interpolation is effected continuously to correct error in case error has developed continuously. The demodulation circuit comprises a counting circuit (11) which detects from the outputs of an error correction circuit (2) how many samples are interpolated continuously, and two AND circuits (9), (10) which perform AND operation of the output of the circuit (11) and a mute signal that is generated when it is out of synchronism with the output. When the samples are to be interpolated continuously more than a given number m, a voice difference signal is muted by the mute signal so that no signal is produced that seriously deteriorates the sound quality.

摘要： A device which receives and displays high-definition television signals and which does not display disturbed image or noise when the input video signals are not high-definition television signals or when the high-definition television signals are interrupted. First signals indicating the synchronization locked state or second signals indicating the synchronization unlocked state are obtained depending upon whether the frame signals are detected or not in the input video signals. When the first signals are obtained, outputs of a signal processing circuit (110) are selected to display high-definition television signals and when the second signals are obtained, outputs of a pattern generating circuit (114) are selected to prevent noise and the like from being displayed.

摘要： In processing the transfer of digital voice signals, an interframe deinterleave switching circuit automatically switches the interleaving length without requiring any switching signal from the external unit. The circuit detects a voice synchronizing signal, produces a switching signal when the voice synchronizing signal is not detected, and inputs the switching signal to an interframe deinterleaving circuit (1) so that the interleaving length is automatically switched in synchronism therewith.

摘要： A circuit for demodulating digital voice signals to suppress the broken noise that generates when the synchronism is no more maintained or when the mute is forcibly applied. The demodulation circuit comprises a synchronism detecting circuit (18) and a muting circuit (17) which mutes the output of an interpolation circuit (16) responsive to a synchronizing lock signal produced from the synchronism detecting circuit (18) when the synchronism is no more maintained. The output of the interpolation circuit (16) that is a differential signal is muted and is then integrated to produce a voice signal of high sound quality without noise even when synchronism is not maintained.

摘要： PURPOSE:To increase the content of oxygen of a natural water area and thereby purify the water by allowing a water current from a natural water area to circulate within a facility for sport purposes, then pumping the water to an area above a tower structure and releasing the water to the natural water area after permitting it to fall. CONSTITUTION:A leisure facility B based on a water stream is built near a natural water area A under environments where a water stream is restricted like a dammed lake or a swamp, or where a water stream is blocked. The water stream conducted from the natural water area A is caused to circulate in the facility B for sport purposes, and part of or the whole water stream is pumped up to an area above a tower structure 5. After that, an aeration phenomenon is generated in the natural water area A by allowing the pumped up water to cascade in the natural water area A. Subsequently, the air is dissolved into the water to increase the content of oxygen in the water of the natural water area A. That is, an extremely satisfactory water purification action takes place.
