PURPOSE:To enable to realize a different type of tone receiver by only changing a memory of a controller, through multi-function of a receiver having filters of an arbotrary order number, by controlling signal flow through the provision of selectors at the input of a digital filter and a buffer memory. CONSTITUTION:The 1st input delaying the output of digital filter 13 through a shift register 14, the 2nd input giving the output of the digital filter 13 through a limiter 15, and the output of the 1st selector selecting the 3rd input being the output of the buffer memory 12 are given to the input of the digital filter 13, and the 1st and 2nd inputs of the 1st selector 16, the output of the digital filter 13, and the output of the 2nd selector 11 selecting the output of an expander 10 expanding the input PCM signal are given to the input of the buffer memory 12 to control each part with the program stored in a ROM of a sequencer 17. |
