Re: gEDA-user: ideal op amps in gschem

OK, I didn't look ahead for the answers - but here's what I think:

1.  It's a frequency dependent load. At low frequency, the load on Vin 
is R2.  At high frequency, the load is 0.

2. If gain is 100, then you can no longer assume V+ equals V-, and the 
circuit won't work the same.  The assumption comes from Vout = Aol (V1 - 
V2), when Aol is large (10^4), Vout/Aol can be ignored and V1 = V2.

3.  not sure

4. also not sure and I'm getting sleepy :-)
