matlab实现Delta-Sigma调制器的频域最小最大优化

The MATLAB codes are based on our recent paper:

M. Nagahara and Y. Yamamoto,

Frequency-Domain Min-Max Optimization of Noise-Shaping Delta-Sigma Modulators,

to appear in IEEE Trans. SP, 2012.

A draft can be down-loaded via:

We give two matlab codes:

[ntf,R]=NTF_MINMAX(order,OSR,Hinf,f0,zf)

[ntf,R]=NTF_MINMAX_MB(order,OSR,Hinf,f,zf)

By these codes, one can obtain lowpass/bandpass (by NTF_MINMAX) and multi-band (by NTF_MINMAX_MB) filters for noise-shaping delta-sigma modulators that minimize the maximum magnitude of the noise transfer function (NTF)

in fixed frequency band(s).
