dbphi

Arguments

db,phi

vector of gains (db) and phases (degrees)

repf

vector of complex frequency response

mod

character string

mod='c'

"continuous" representation between -infinity and +360 degrees (default)

mod='m'

representation between -360 and 0 degrees

Description

db(k) is the magnitude of repf(k) expressed in dB i.e. db(k)=20*log(abs(repf(k)))/log(10) and phi(k) is the phase of repf(k) expressed in degrees.
