摘要： A timing recovering apparatus comprises an equalizer for equalizing a digital data signal subjected to interleaved NRZI such that the digital data signal has partial response (1, 0, -1), two comparators for comparing the equalized data signal with two different reference levels, two phase comparing portions for detecting phase difference between the outputs of the comparators and a reproduced clock signal separately, an adder for summing the outputs of the phase comparators, and a VCO for generating the reproduce clock signal in accordance with the output of the adder. This timing recovering apparatus performs phase comparing with two different phase comparators and PLL control is performed on the sum of the outputs of the two different phase comparators, so that the clock signal is not affected by data pattern of the data signal. An automatic slice apparatus comprises the equalizer for equalizing a digital data signal subjected to interleaved NRZI, and two comparators supplied with reference levels, and the timing recovering apparatus, detects amplitude of the output of the equalizer in response to the reproduced clock signal to compensate the reference levels.

摘要： A delay circuit is provided with an npn type of transistor of which a base is connected to an input terminal, a first constant current source through which a constant current flows from an emitter of the transistor to ground, a first capacitor arranged between the emitter of the transistor and an electric source terminal, a second capacitor C.sub.22 arranged between a collector of the transistor and an output terminal, a first resistor arranged between the emitter of the transistor and the output terminal, a second resistor arranged between the collector of the transistor and the electric source terminal. The constant current of the constant current source is changeable, and an emitter resistance of the transistor is changed depending on the constant current. Therefore, an analog signal applied to the input terminal is changeably delayed by coaction of the resistors, the capacitors and the emitter resistance adjusted by changing the constant current of the constant current source.
