Circuit simulation and software workbooks like Matlab and Jupyter are great for being able to build things without a lot of overhead. But these all have some learning curve and often use clever tricks ...

Imagine how a phone call works: Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard ...

Why electrical circuits operating at optical frequencies is an attractive opportunity. How a new plasmonic arrangement is used to mix electrical signals at optical frequencies. The advantages and ...

A team of physicists and engineers at Lawrence Berkeley National Laboratory (Berkeley Lab) successfully demonstrated the feasibility of low-cost and high-performance radio frequency modules for qubit ...

A software-defined radio (SDR) uses a general-purpose computer processor to perform aspects of digital signal processing in place of analog circuit hardware. This allows for greater flexibility in ...
