Multiple signals can be transmitted between two locations at the same time by making a minor adjustment to the receiver circuit. An additional DG508A is employed as a demultiplexer, enabling continuous monitoring of all 8 channels.

To implement a system for simultaneous signal transmission, the receiver circuit must be designed to accommodate multiple inputs without interference. This can be achieved by modifying the input stage to include a second DG508A integrated circuit, which functions as a demultiplexer. The DG508A is a low-power, dual 4-channel analog multiplexer/demultiplexer that can route signals effectively.

In this configuration, each of the 8 channels can be monitored continuously, allowing for real-time analysis of the signals being transmitted. The demultiplexer operates by selecting one of the input channels based on control signals, which can be generated by a microcontroller or other control circuitry. This allows the system to switch between channels rapidly, ensuring that all signals are captured and processed without delay.

The design should include appropriate filtering and signal conditioning components to maintain signal integrity, especially if the signals are analog in nature. Additionally, careful consideration should be given to the power supply requirements of the DG508A and the overall circuit to ensure reliable operation.

By utilizing this approach, the system can efficiently manage multiple signal paths, enhancing the overall capability of the communication system. Proper layout and grounding techniques should also be employed to minimize noise and cross-talk between channels, further improving performance.A number of signals may be sent between two points simultaneously by making a slight modification in the receiver circuit. A second DG508A is used as a demultiplexer, allowing all 8 channels to be monitored continuously.
