Y = log10(X) returns the common logarithm of each element in array X. The function accepts both real and complex inputs. For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf,Inf). For complex and negative real values of X, the log10 function returns complex values.

Answers (1) 1. pwelch uses Welch method, which involves windowing and averaging on top of fft, that's why they are different. The basic shape is probably similar but FFT probably gives you the best resolution while pwelch provides smoother spectrum. 2. 10*log10 is the conversion to dB.
