Right. To understand this, it's important to realize that filters implemented in DSP are simply digital simulations of ordinary analog filters -- in this case, resonant circuits tuned for the desired frequency and bandwidth. Ideally, well-designed sets of filters should combine to yield minimal ripple in their amplitude and phase response if all (or adjacent bands) are set to the same gain. The extent to which this is achieved depends on the circuits that they are simulating, and some circuits are far better than others in this regard. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
