In Reply to: Transfer function again. posted by Mark Kelly on December 2, 2005 at 21:46:16:
That certainly sheds a lot of light on the subject. Thanks for showing me the way, and for the url. I'll download gnucap and gwave and play around with them when I have some time. I always thought that the very high "gain" spec for the phonocube was for old very low output MCs like the Ortofon MC20 with output spec of 0.07mV. (How much gain would they need from a voltage amplifier?)How did you calculate the transfer function? Of course it has something to do with the resistance from the opamp's -ve input to its output (in the link called RF). Is the transfer function simply equal to this resistance?
