A new technical paper titled “Three-to-one analog signal modulation with a single back-bias-controlled reconfigurable transistor” was published by researchers at NaMLab gGmbH, GlobalFoundries, and TU ...
Wide bandwidth radio transmitters commonly use analog quadrature modulators (AQMs) to convert complex (I + j*Q) baseband signals to radio frequencies (RF). An AQM consists of a local oscillator (LO) ...
XM has applied for a U.S. patent on a new method of FM modulation. Currently most cars do not include any kind of an auxiliary jack, so the method of choice for satellite radio is through FM ...
