Hi Bill,<\/b><\/span><\/div>\n
Thought I would drop you a brief note. <\/span><\/span>I have been catching up on my listening to past issues of Soldersmoke podcasts and was particularly interested in the discussion between you and Pete concerning the simplicity associated with non-digital, integrated circuits and microprocessors and all of the rest of the very small miniaturized circuit elements.<\/span> <\/span>You rightly pointed out that you desired (along with a lot of the rest of us) to fully understand what was going on in a circuit and for that reason desired to maintain the simplicity of transistor and discrete components in your design and build projects.<\/span> <\/span><\/b><\/span><\/div>\n
<\/span>I agree with you completely but offer the alternative to the simple circuits in the form of the attached simple diagram of the signal flow path in a digital radio. I found this some time ago in a digital electronics magazine and thought you and Pete would find it interesting.<\/span> <\/span>Perhaps this might be something to spring on Pete on 4-1-2018.<\/span><\/b><\/span><\/div>\n
Take care and thanks to both of you for many pleasant and thoughtful hours of enjoyment listening to Soldersmoke!<\/b><\/span><\/div>\n
All for now, 73,<\/b><\/span><\/div>\n

Allan, <\/span><\/span>WA9IRS<\/span><\/b><\/span><\/div>\n
My response: <\/span><\/b><\/span><\/div>\n
Thanks Allan, Very illuminating. It is all clear to me now. I feel so much better. FB OM. 73 Bill <\/b><\/span><\/div>\n
