[sdiy] Drum sample playback

[Tom Wiltshire]

Speaking from the position of a non-master, simulations are what I do when I can't "get down to transfer functions", as you so nicely put it. The sims are a good way of getting the computer to do the hard sums and just tell me the answers. I can plug bits together in a simulator (LTSpice in my case - free!) just the same as in a breadboard and it can do the tough stuff of working out frequency responses and gain values and whathaveyou.

I have resolved myself to looking at electronics as a wonderful art form more than a mathematical challenge. I can't imagine what things would be like without all of the brilliant people in electronics doing all of the hard work for me. I would be a plumber.

Granted, transistors are so general that you're not going to see every potential circuit in their data sheets, but as you get to more complex circuits like a transconductance amplifier you'll learn a lot from the manufacturer. Of course, the same comment could be made about this approach as about textbooks: does it matter whether you copy a design that almost surely came straight out of the manufacturer application notes or go directly to the original notes yourself?

There are many parts of circuits that are only appropriate for the situation at hand, and your application might be rather different. You really need to read and understand how a circuit works before you know whether it's appropriate for your new design.
