    • An electronic sphygmonanometer comprises a K-sound detection circuit (SD) for detecting Koroktoff sound from a microphone, a pressure transducer (17) for converting pressure to an electric signal, a pressure pulse detection circuit (20) for detecting a pressure pulse signal from the electric signal and a double integral type converter for converting an analog output of an amplifier (18) to a digital signal. An arithmetic unit (11) receives the output signals of the K-sound detection circuit (SD), the pressure pulse detection circuit (20) and the converter (8) drives a display device (12) for indicating systolic and diastolic pressures digitally. A detection circuit (S) includes the K-sound detection circuit (SD), the pressure transducer (17), the amplifier (18), the pressure pulse detection circuit (20) and an analog section (19a) of the converter. A logic circuit (L) includes a digital section (19b) of the converter (8), the arithmetic unit (11) and the digital display (12). A plurality of signal lines (WR) connected between the detection circuit (S) and the logic circuit (L) and include a first signal line (S5) for transmitting the output signal from the K-sound detection circuit to the arithmetic unit, a second signal line (S4) for transmitting the output of the pressure pulse detection circuit (20) to the analog section (19a) and a third signal line (S1, S3) for transmitting an output of the analog section (19a) to the digital section (19b).
