Abstract (in Japanese) (See Japanese page) 
(in English) This paper implements adaptive notch filters with constrained poles and zeros (CPZ-ANFs) using fixed-point DSP. Since the CPZ-ANFs have narrow notch width, direct-form II structure suffers from high probability of overflow in its internal state. Hence we use direct-form I structure in implementation of the CPZ-ANFs. Experimental results show that our method allows the CPZ-ANFs to operate properly on the fixed-point DSP.
