fW – IQClab

The function $W=fW(\tau_\mathrm{max},glf,type,T_s)$ generates weighting functions that “cover” the delay operator $e^{-i\omega \tau_\mathrm{max} }-1$ . The inputs should be specified as follows:

$\tau_\mathrm{max}>0$ is the maximum time delay.
$glf>0$ specifies the gain at low frequencies.
is the type of weight. There are three types of weights that can be considered:
- $type=1$ : Minimal gain of $W$ at high frequencies
- $type=2$ : Maximum bandwidth of $W$
- $type=3$ : Both options together at the cost of a McMillan degree increase of 1.
$T_s$ is the sampling time. If $T_s>0$ , $\tau_\mathrm{max}$ should be an integer, denoting the number of delay samples.
