Blog about Noise and how to kill it?

[x18]

hi dave.

because you got a tektronix 2225. i think a blog about noise and accuracy would be great. you could show techniques how to kill noise on the supply lines and all the other dc signals in a circuit where you need stable and accurate signals. this would be a great theme for showing those techniques in practice and not only dry theory.
also i would be interested in the tektronix 2225 scope and if it is able to analyse the noise and if its worth buying one in reference to analysing and killing noise in a circuit.
