FAQs
What is precoding? What does it do?
Precoding is a signal processing technique that modifies the phases and amplitudes of wireless signals to combat channel distortion and optimize the quality and reliability of data … Read about What is precoding? What does it do?
How do snubber circuits offer circuit protection in power electronics?
Snubber circuits are commonly connected across semiconductor switches for protection. Common ways of protection include suppressing V-I spikes and ringing, complying with SOA, resonance … Read about How do snubber circuits offer circuit protection in power electronics?
FAQ on the bias tee
A conceptually simple passive component is used to combine or split DC and RF signals; however, its implementation has many subtleties. The RF world, operating at hundreds of megahertz and … Read about FAQ on the bias tee
What’s the relationship between Ohm’s Law and quantum mechanics?
Ohm’s Law is the classical physics explanation of the linear relationship between voltage, current, and resistance in a conductor. Quantum mechanics provides insights into the mechanisms behind … Read about What’s the relationship between Ohm’s Law and quantum mechanics?
