- Reasons to use 50-ohm termination include12345:
- Provides a perfect transmission by absorbing all energy in the returning electromagnetic field, preventing reflection.
- Balances maximum power transfer, voltage sensing, and minimized loss in coaxial cables.
- Ensures proper network connectivity in 10BASE2 networks.
- Good compromise for power and voltage in transmitter applications.
- Prevents signal doubling and maintains correct voltage levels.

The 50-ohm termination absorbs all the energy in the returning EM field so there is no reflection. This means that the circuit is stable at +5 volts. When the signal switches from a logic 1 to a logic 0, the same events take place.resources.altium.com/p/using-terminations-control-…In short, it originates from the use of long coaxial cables as transmission lines for radio signals. A 50 Ohm characteristic impedance for a dielectric-filled coaxial cable provides the best balance between maximum power transfer down the line, maximum voltage sensed at the output, and minimized loss.resources.system-analysis.cadence.com/blog/msa…10BASE2 networks absolutely must have proper termination with a 50 ohm BNC terminator. If the bus network is not properly terminated, too much power will be reflected, causing all of the computers on the bus to lose network connectivity.en.wikipedia.org/wiki/Electrical_terminationThe 50 Ω value is a good compromise for power and voltage, such as that output by a transmitter. In contrast, for situations where low attenuation is the primary goal, such as with low-level signals from an antenna or an analog video link, 75 Ω is a better choice.www.digikey.com/en/blog/the-reasons-for-50-ohm-…If you don't use 50-Ohm termination, the signal "doubles" as compared to what the signal generator dial assumes (although there could be scaling options depending on assumed termination setup. But is done for dial convenience only). If you load the other cable end with 50-Ohm terminator, the voltage will be half of that.electronics.stackexchange.com/questions/394844/… - People also ask
