bandpass minima (all such minima are equal in a Chebyshev filter). The cutoff frequency coincides with the corner ("nominal") frequencyonlyin the case of a "natural" Chebyshev filter (like the 1.25 dB second-order Chebyshev filterplottedabove). For high-ripple Chebyshev filters, the cutoff ...
For example, noise detector 120 may be a set of bandpass filters and one or more circuits that measure the energy in several different frequency bands. At block 610 noise energy profiler 125 analyzes the noise identified in block 605. For example, noise may be analyzed to identify a ...
