AMI Semiconductor released
a reference design
for a DSP-based electronic stethoscope today. The advantages offered
by this technology includes improved clarity, amplification, and the
ability to store and play back multiple samples. Vendors like
3M/Littmann, Welch Allyn and others may find this reference design of
After a quick scan of the
behind the reference design, we find the following features:
- DSP that supports user interface, local data
storage/retrieval and software-based signal processing and
- Very low power consumption with "smart"
connectivity for LCD and wireless (Bluetooth)
- Extended product life cycles suitable for embedded medical
Sounds like the makings of a nice wireless sensor
platform, doesn't it?
