摘要
To obtain a band pass delta sigma modulator (excluding θ0−±(π/2)×n; n is an integer being 1 or greater) for a desired frequency by replacing z in a z domain model of a low pass delta-sigma modulator with z′ below:; z′=fcnv(z,θ0), whereinfcnv(z, θ0) is a function in which the absolute value of fcnv(z, θ0) is always 1 for any z and θ0,; θ0=2π×(f0/fs),fs is a sampling frequency, andf0 is a center frequency of a quantization noise stop band of the band pass delta-sigma modulator.展开▼
