dbphi
frequency response to phase and magnitude representation
Syntax
[db, phi] = dbphi(repf [, mod])
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.
