Re: Couples Therapy
Hi Antonio,
Thank you for your comprehensive answer. At first I was a little surprised
with your first comment: 'I don't see any relation between the theory of
coupled bandpass filters and Tesla
transformers.', but apparently you didn't meant it like it sounded. I
understand the need for resistor(s) in a bandpass filter to make it suitable
for its job, but do you mean with 'this condition' the moment of critical
coupling? I don't think resistors can have any influence on the moment a
bandpass filter has the transition from one peak to two peaks in the dB/f
graph.
