摘要： A filter adjustment apparatus adjusts the properties of a filter by changing, for example, the circuit constants of a filter connected in series with a signal processing circuit to correspond with desired optimum properties of the filter. The state of the signal processing circuit is changed to a state not affecting the filter adjustment, to thereby eliminate the influence of the signal processing circuit on the filter characteristics, to facilitate and increase precision of the filter adjustment.

摘要： An ultrasonic blood stream observing apparatus based on a pulse Doppler method utilizing as a transmission, a high frequency pulse signal. The frequency f.sub.PRF of a transmission pulse repetition signal and the frequency f.sub.R of a reference signal used for demodulating a Doppler component of an observed signal, are synchronized to each other. The frequency f.sub.PRF is a harmonic frequency. The output of an oscillator is frequency-divided to produce the transmission pulse repetition signal. A frequency multiplier generates an output signal used as the reference signal, synchronized to the transmission pulse repetition signal. The frequency multiplier frequency multiplies by n its input signal obtained directly or indirectly from the oscillator.
