Errata for Part 3 lecture notes. Page numbers based on the student version with Neuhoff #s, not Ulrich #s. p.7 in 2nd to last exponent at bottom, the .1 should be 0.2 p.8 The spectrum frequencies in the bracketed list should all be divided by 2pi because we are using "f" not omega in such lists. p.16 the derivation of parseval is correct, BUT putting the "T" on the "wrong side" adds unnecessary confusion.
