Title: Pulse amplifying circuit
Inventor: SEKI NAGATAKA
IPC: H03K17/64
Filed: 1980-03-27
Abstract: PURPOSE: To reduce power consumption and to improve reliability by charging a capacitor with the stored energy of a pulse transformer.  
     CONSTITUTION: When transistor 17 turns on, voltage EC is applied between points B and C and the potential at point A reaches 2EC. Diode 12 is biased reverse and no current flows from power source 11. Voltage E/n 1  is developed across the secondary winding 16. Then, when capacitor C is discharged and the across voltage of C reaches E/2, the potential at point A reaches E and as it further drops, diode 12 conducts, so that it is decreased to voltage E/2n 1  of the secondary winding. Then, when the transistor turns off, capacitor C is charged again and the energizing current of the primary winding 15 1  flows into C. Consequently, EC≈2E 1 .

Filed: 1989-02-16
Abstract: PURPOSE:To reduce the cost of system constitution and to effectively eliminate the distortion of a sound signal, by estimating the noise transmission function of a partial band from the signal extracted from a partial band extracting means, and producing the pseudo noise component of an entire band to eliminate the noise component of the output signal. CONSTITUTION:The noise transmission function is estimated from the extracted signal that is a prescribed partial band extracted from the output signals of the 1st and 2nd microphones 11 and 12. Thus a pseudo noise component is obtained and sent back to an entire band of the output signal for production of the pseudo noise component of the entire area. Then, the pseudo noise component of the entire band is extracted from the output signal of the microphone 12 so that the noise component is deleted from the output signal. Thus a filter having the equivalently large tap length is obtained by using the filters 16, 17 and 23 having each prescribed partial band with high efficiency. As a result, the cost of the system constitution is reduced and at the same time the distortion of the sound signals can be effectively eliminated.
