This invention provides a compound of the formula (I): And their use for the treatment of disease conditions caused by overactivation of the VR1 receptor such as pain, or the like in mammal. This invention also provides a pharmaceutical composition comprising the above compound. 

Substituted N-bicyclicalkyl bicycliccarboxyamide compounds

A digital audio signal demodulation circuit comprises a synchronous detection circuit (18) and a muting circuit (17) for muting the output from an interpolation circuit (16) using a synchronization lock signal generated from the synchronous detection circuit (18) when synchronization has been lost. The differential signal output from the interpolation circuit (16) is muted by the muting circuit (17) and thereafter integrated by an integration circuit (19). Thus, an audio signal with high sound quality can be demodulated without producing interruption noise even when synchronization has been lost or forcible muting is done.
