Thanks Frank -- I remember using transistor-based analog computers at collage in the late 1970s -- I wish I coudl go back and show myself things like MP3 players (and tell myself to buy stock in Apple and SanDisk and... (grin)
The first single-chip DSP processor came from Bell Labs in 1979, but building block compenents came earlier -- Fairchild had a 2x4 multiplier IC in 1970.
It's difficult to discover the first usage of the phrase "digital signal processing," but it is worth noting that the first A/D and D/A converters were developed using vacuum tubes in the late 1930s.
I tell you, I wish I had learned more about digital signal processing when I was younger ... but now I come to think about it I don't even know if there was such a beast when I was at college in the late 1970s. Does anyone know when the term DSP first appeared on the scene?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
