Inventor: OONISHI TAKESHI
IPC: H03M13/00
Filed: 1981-03-25
Abstract: PURPOSE:To eliminate erroneous corrections, by detecting a CRC overlooking error through detections of three syndrome values, and by generating a control signal. CONSTITUTION:A zero detecting circuit 19 detects that a syndrome S1=An(+) An+1(+)Bn+1(+)An+2(+)Bn+2(+)Pn=0. Another zero detecting circuit 20 detects that T<i-7>S2=0 (from T<i-7>not equal to 0.1<=i<=6, S2=T<6>An(+)T<5>Bn(+) T<4>An+1(+)T<3>Bn+1(+)T<2>An+2(+) TBn+2(+)Qn=0). The other zero detecting circuit 21 detect that a syndrome Si= S1+T<i-7>S2=0. Then, when the CRC pointer number of a sampling signal word is 1 (one) and S1not equal to 0, S2not equal to 0, and Sinot equal to 0, this circuit judges that an overlooking error takes place and generates a control signal.

Abstract: PURPOSE:To generate surely a call tone even at power failure by connecting a speaker in series with a negative feedback loop of an amplifier circuit and connecting an output of a ringer circuit in parallel with the negative feedback loop of the amplifier circuit. CONSTITUTION:The speaker 6 is connected in series with the negative feedback loop of the amplifier circuit 1 and an output of the ringer circuit 5 is connected in parallel with the negative feedback loop via a matching transformer 7. When it is supported that the resistance value of a resistor 8 between the negative loop of the amplifier circuit 1 and an earth potential is R, then a current of vin/R flows at the input of an input signal vin and having the quantity proportional to the vin is generated.
