[SI-LIST] Re: (no subject)

Hi Vince,

To answer your first question, assuming that you are looking for the power 
dissipation of an IC package for instance, there can also be power 
dissipated internally from the inputs although typically minimal but 
outputs can dissipate power as well from sources different from the VCC and 
current going into your circuit.

Your second question is somewhat broad.  I think both are used depending on 
the receiver and the circuit or where in the circuit.  For instance I can 
envision a series LC where I want to pass a band of frequencies and a 
parallel LC where I would want to reject a band of frequencies.  More often 
what's used are combinations of LC's to make a modern LP, HP BP, 
filter.  Perhaps you can specify where in the receiver you are interested: 
preamp, IF, LO, mixers, etc.
