The book treats the subject of estimation of the vibration characteristics of machines that use synchronic transformation. It describes the problem of synchronization through kinematical processes related to the cycle to aid non-parametrical and parametrical identification of internal vibration processes, which is practical for the monitoring of the technical condition of the machine. Much attention is paid to current demodulation of the machine signal, which uses adaptation methods. This work is useful for the students of sound-control and machine operation, as well as to engineers and researchers interested in technical diagnostics.
