Abstract

A cyclic switch is used to switch ten channels with electrical signals between zero and ten megahertz. Each channel may have its signal amplified, frequency corrected and also corrected according to the length of the cable used. The duration of connection between input and output of a channel may also be varied between 3 and 90 seconds. The switch has two output channels. The switch has ten channels and also ten circuits with video amplifiers and frequency correctors. It also has a counter circuit, a supply circuit and a time-base circuit. The switch may be operated manually or by telecontrol. The switch may be communication or measuring equipment requiring a preset switching of signals.
