Galileo published his discovery of the isochronous property of the pendulum in 1639.
Musical tones are produced by isochronous (equal-timed) vibrations of the vocal organs continued for some length of time.
If the impulses are not isochronous, the intensity of the note is increased.
Hence it is that the vibrations of unequal weights are isochronous when hung on strings of equal lengths.
The vibration being, of course, isochronous, any change of pressure merely produces a shortening or lengthening of the stroke.
If the circuits have the same frequency when separated they are said to be isochronous.
Or again by suitable arrangements the bob may be made to move in certain curves so as to be isochronous.
