Abstract
An oscillating apparatus allowing for synchronization to an external sinusoidal source, and in which a unidirectional element is so located that the oscillating device may be replaced without the necessity of altering circuit elements to maintained synchronization and the desired nominal frequency of operation.
Claims4
An oscillating apparatus comprising:
- timing means for providing timing signals;
- a first unidirectional current conductive means having an input terminal and an output terminal, coupled to said timing means at said input terminal, and so poled that currents are conducted from said input terminal to said output terminal;
- a second unidirectional current conductive means, having an input terminal and an output terminal, said input terminal coupled to said output terminal of said first unidirectional current conductive means thereby forming a first node;
- a first capacitor, having a first terminal and a second terminal, said first terminal coupled to said first node, said first capacitor with said timing means determining a timing signal at said first node;
- means coupled to said second terminal of said first capacitor for supplying synchronizing signals so that the sum of said timing signals and said synchronizing signals exists at said first node;
- and
- oscillating means, coupled to said output terminal of said second unidirectional current conductive means, for causing oscillations having a frequency dependent on said sum of said timing and synchronizing signals at said first node.
