Re: Memcals
I'm not EE illiterate but I barely
remember doing a few calcs with rc
circuits used as integrators and
differentiators and am wondering if
there are any caps in the netres. I'd
like to see the schematic.with just
resistors it may be strictly a 'linear'
circuit for limping home.I would assume
that a base pulse width is generated
somewhere to feed the circuit and it may
be possible to adjust it.'748... is that
what's in an '88 2.5l s-10 by any
chance.
