4.5Mhz notch filter

Posted on Oct 18, 2012

Component value sensitivityis extremely critical, as are temperature coefficients and matching of the components. Best performance is attained when perfectly matched components are used and when the gain of the amplifier is unity

To illustrate, the quality factor Q is very high as amplifier gain approaches 1 with all components matched (in fact, theoretically it approaches «) but decreases to about 12 with the amplifier gain at 08.
