Good books for circut ideas?

[Anonymous]

Do any of the participants of this forum know of a really good book on snippets of electronic circuits?
For example-a circuit that is a sample & hold that will take a return pulse of a PI, sample it-put into a shift register-thru a an ADC convertor and store it as a byte. Then use that value in look up table.
In general-I see I see this as a rather elegant solution to the whole lack of discrimination with PI units.
In all the discussions I have seen so far & there are far better heads than my own (Eric) Dave Emory et al- I see Firmware (software) as the solution to some of the PI's shortcomings.
I have noticed that when a microcontroler is used-it is for pulse delay etc-sort of what a 555 timer might do.
Small eight bit micros can really do a whole lot more than that.

This has been done long ago by Anthony Barringer of Barringer Associates (see patents:3,852,659 and 4,506,225). This is something that Eric would be a revolutionary to incorporate on his next gold machine as the technology enabled Barringer Associates to be one of Canada's most successfull Mineral Exploration company's credited with hundreds of undiscovered mineral deposits. The first patent has expired for sure so beats the heck out of me why Bruce Candy or Mr. Foster hasn't used it. Just my opinion.
