This old-time, multi-transistor Sony TFM-6100W AM/FM radio may be an antique, but it provides a frame of reference to show how far radio technology and products have come in a few decades.
Cars are incorporating radar and other external-facing signal, and may soon have intervehicle data links; they may soon be the victims of deliberate jamming, thus requiring electronic countermeasures.
Reality check: Often what appears “on paper” to be a simple, trivial interconnect effort turns out to have real-world installation issues which require some extra time and attention, if not frustration.
Today’s cars are loaded with sensors and analog signal-conditioning components for basic operation, user convenience, and safety mandates, but there’s an upfront cost and complexity impact as well as longer-term implications that comes with these enhancements.
Silicon is a viable substrate for functions such as optical waveguides; a building block of interesting applications such as optical phased-arrays and lenless cameras.
