.SH NAME
dbphi - frequency response to phase and magnitude representation 
.SH CALLING SEQUENCE
.nf
[db,phi] =dbphi(repf)
.fi
.SH PARAMETERS
.TP
db,phi         
: vector of gains (db) and phases (degrees)
.TP
repf       
: vector of complex frequency response
.SH DESCRIPTION
.LP
\fVdb(k)\fR is the magnitude of \fVrepf(k)\fR expressed in dB i.e.
\fVdb(k)=20*log(abs(repf(k)))/log(10)\fR and \fVphi(k)\fR is the phase
of \fVrepf(k)\fR expressed in degrees.
