Surface and image plots of waveform variations in V1-V6 leads. First, please read the disclaimer page . Target amplification is from uV input to about 1.5 VPP output. Currently the output of a single amplifier stage can be connected to one channel of the stereo sound input jack of the Macintosh, using the internal ADC chips to perform analog to digital conversion. Photos, schematics, and test results are provided for all amplifiers.
All amps use the same power supply layout.
By the latter, I mean that while the prototypes look pretty ugly, they seem to work just fine. Of course, once you have the final schematic, you can build the circuit any way you want, and make it as pretty as you like. Circuits Power supply. Active low-pass filtration. Data acquisition on the Macintosh.
