Using Bi-directional Couplers to Reconstruct a Radio Signal

We need to observe an unknown transmitted signal coming out of a Software-Defined Radio. We do this by inserting a probe between the radio and its antenna. The primary problem antenna itself can reflect the signal and pick up interference, but these unwanted signals can be filtered out with the use of a special probe: a bidirectional coupler.

Bias Lighting

What better accessory to a new PC build than bias lighting? The ambient glow not only welcomes you to waste your time gaming into the early hours of the morning, but it’s also better for your eyes as it softens the edges of your screen.
