PHASE DIFFERENCE MEASURING DEVICE

摘要

Device for measuring the phase difference between two alternating-voltage signals. These alternating-voltage signals are transformed into sawtooth voltages having equal peak-to-peak values. In an adder there is added to the difference between these sawtooth voltages a voltage which is derived from a direct-voltage supply source via a switching member which is switched at instants which correspond to the steep edges of the two sawtooth voltages, the arrangement being such that the adder delivers a direct voltage proportional to the phase difference between the two sawtooth voltages. The invention is of particular importance for a device for generating two triangular voltages having an adjustable phase difference.
