Title: Impulse noise rejector
Inventor: KOUNO TOSHIHIKO
IPC: H03G3/34
Filed: 1980-06-13
Abstract: PURPOSE:To reject impulse noise without giving much damage to an original signal, by outputting an input signal as it is when no impulse noise is superimposed and rejecting the high-frequency band component by noise period if any impulse noise is superimposed. CONSTITUTION:An input signal is respectively applied to low- and high-pass filters 11, 12 via a buffer 20 and a delay circuit 21. On the other hand, the impulse noise component included in a music signal in the buffer 20 is detected at an impulse detecting circuit 22 and applied to a switch circuit 14 as a control signal via a driving circuit 23. The low-pass filter 11 has a transfer function F(s) as shown in (a) which rejects impulse noises. Further, since the high-pass filter 12 has a complementary transfer function 1-F(s) as shown in (b), the contact of a switch 14 is closed if no impulse noise is included in the music signal, allowing to reject impulse noises effectively without giving damage to the music signal as shown in (c).

Filed: 1989-04-03
Abstract: PURPOSE:To set a compromised value for the main beam of a transmitting and receiving beam profile at a zero radiation angle and a side lobe by imparting a variable setting function of the amplitude of an exciting pulse voltage to a transmitter, and imparting a variable setting function for an amplitude to a receiving preamplifier. CONSTITUTION:A transmitting voltage VXPP is set with a transmitting-voltage setting signal 311 from a digital scan converter (DSC) 1A for a variable exciting- pulse-voltage amplitude circuit 40. A delayed transmitting timing pulse 302 is inputted into the circuit 40. The height of a pulse corresponding to an output VXFF is set. When an output VP of the circuit 40 is inputted into a transmitter 4, a current Ie flows through the secondary side of a transformer T1. A current which is proportional to the current Ie flows through the primary side of T1. Thus an ultrasonic wave probe 5 is excited. The intensity of the pressure of the sound wave emitted from the probe 5 is proportional to a voltage VK across both ends. VK is made variable by controlling a pulse height VP corresponding to VCC2. Meanwhile, the voltage at the secondary side of the transformer T1 is amplified in a variable gain type preamplifier, and a voltage level required for a processing circuit at the succeeding stage is obtained.
