Analog signals are transmitted as electrical waves.
Analog signals are transmitted as electrical waves.
Electrical signals are transmitted from one place to another through conductive materials, such as copper wires. These materials provide a path for the signals to travel, and the signals are modulated to carry information. In some cases, signals can also be transmitted wirelessly through electromagnetic waves.
synapes
yes
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
They are pheromones.
each channel can only transmit signals in one direction signals are transmitted as rf waves can be used to transmit multiple signals at once

radio waves radiation
Light.
It signals the difference between successive sample sizes
Sound is transmitted via telegraph by converting sound waves into electrical signals. These electrical signals are then sent through a telegraph wire to a receiver on the other end. The receiver converts the electrical signals back into sound waves, allowing the message to be heard.
