circuit design and analysis
« on: July 24, 2015, 08:43:38 pm »
I am wanting to get better at design and analysis. what resources could I use to achieve this? I understand components by themselves,but when I try to understand them together I usually go blank when I see a complete schematic.

you can build it and investigate it. Usually a circuit can be broken into blocks who's response is known

+1 for building and measuring whatever combination interests you in blocks or pieces at a time - try different test points and different value components until it becomes clear what is causing what.

When you run into something that needs explanation, if the Internet in general doesn't help, try searching YouTube - it's a pretty amazing resource; a picture is worth a thousand words and video is worth about 24-30 pictures (frames) per second :)

If that doesn't clear things up and you can post a very specific question (and maybe include some images or schematics of the circuit in question) there are probably lots of people here who can help sort it out.

Sometimes it just takes time.

There are certain "design patterns" which you learn to recognise, e.g. a common-emitter amplifier, a low pass filter, a logarithmic amplifier, etc etc etc. Learning to recognise those can only be done the hard way, and it is easily thwarted by ignorant b*******ds that don't draw the circuit in a way that highlights the pattern. There are too many of those nowadays, and there is a special circle of hell reserved for those that have inputs on the right and outputs on the left.

Often the best help is a circuit description which mentions the design pattern by name.

There are lies, damned lies, statistics - and ADC/DAC specs.

1. Read "The Art of Electronics" (2nd edition is good enough if you need to save money)

2. Install LTSPICE and run the examples
