Title: Digital/analog converting circuit and regenerator using the same
Inventor: MICHIYOSHI HIROSHI
IPC: G10L19/00
Filed: 2000-09-05
Abstract: PROBLEM TO BE SOLVED: To provide a digital/analog converting circuit which can check the occurrence of specified noise by adding a simple circuit without performing the addition of a mute circuit or the reset of an integrator. SOLUTION: This is a digital/analog converting circuit having a ΔΣmodulation-type noise shaping quentization loop for converting an oversampled multibit input signal into a digital signal with a reduced number of bits, and a means for converting the digital signal with a reduced number of bits mentioned above into an analog signal. This circuit is equipped with a time series register 33 which receives the input of an integrator which retains the quantization error within the above ΔΣ modulation-type noise shaping quantization loop, a circuit 34 which judges the signal inclination of the input signal by comparing the output patterns of the integrator from the time series resistor 33, and a circuit 35 which judges the error value.  If the residual error of the integrator is in positive state, this reduces the residual errors of the integrator gradually, and if it is in negative state, this increases the residual error of the integrator gradually.
