Abstract:
A circuit for the conversion of analog signals into logic values, said circuit comprising:an analog signal input, a circuit for establishing a mean value receiving the signal present at the analog signal input to establish a mean value of this signal, and a threshold comparator having a first input and a second input, and receiving the mean value as a threshold value at the second input, wherein the circuit for establishing a mean value comprises at least one resistor with a value R series-connected with a capacitor with a value C, and wherein a phase-shifter circuit is interposed between the signal input and the first input of the comparator, the phase-shifter circuit comprising at least one resistor and one capacitor having values of R and C which are tha same as the values of R and C of the at least one resistor and capacitance of the mean value circuit, and possessing a transfer function H equal to (1âˆ’RCp)/(1+RCp) where p is the Laplace variable.
