Oscillation analysis system for dynamic objects - has switching system for variable gain amplifier and dephasing unit

摘要

An oscillation analysis system for an object in a dynamic state has a variable gain amplifier (3) for difference signals connected to an indicator (4) and an adjustable dephasing unit (5) connected by a periodic switching system (6) to the oscillation source (1) and the object (2) in the dynamic state, so that phase angle, the speed of operation, the signal amplitude and also one capacitance and inductance of the elements of the oscillations can be monitored. The dephasing unit (5) has a summer and operational amplifier in parallel, and a negative raction circuit which has a variable capacitor and a resistance in parallel.
