[Technical specificity of synchronous registration of pulse].

Analyzed in the paper is mutual influence of channels in synchronous registration of pulse signals from human radial arteries made by a device whose transducers share a common base. Such influence is conditioned by the base mobility, which in its turn is caused by the fact that the device rests on soft tissues of the hand and that the fixation elements work by cross rigidity. Transducers must be fixed separately and the impact of their initial force on signal registration zones needs to be eliminated by design-based separation of zones of registration and fixation to enable the use of radiophysical methods in signal processing.
