It's rare that we have only one way in which to approach a particular topic?fortunately, spectrum estimation isn't one of those rare cases. In the most recent article of this series, we considered the periodogram and correlogram estimators for the power spectral density (PSD) function. However, they are only two of several possibilities. In this installment, we consider two additional kinds of spectrum estimates: autoregressive (AR) estimates and the maximum entropy (ME) method.
