Title: Partial oscillator field through erasing circuit
Inventor: CHIYAARUSU AARU HOWAITO
IPC: H04B1/10
Filed: 1989-06-20
Abstract: PURPOSE: To eliminate the need for an expensive circuit component by comparing one signal part of a local oscillator(LO) with an IF signal, up-converting the IF signal shifting the phase so as to conduct compensation with consistency without manual adjustment. CONSTITUTION: A circuit 11 receives an LO signal used to apply up-conversion to one IF signal or over and gives the signal to mixers 15, 17, in which IF signals are coupled with the LO input signal and the IF signals are up-converted. Phase elimination is conducted by giving outputs from the mixers 15, 17 to a phase shift coupler 19, in which one of the inputs to the coupler 19 is phase- shifted by 90 deg.. That is, a phase shift by 90 deg. is obtained between LO feed-through signal outputs from the mixers 15, 17 and the remaining 90 deg. phase shift is conducted by the coupler 19. Thus, any expensive circuit component is not required.

Inventor: ICHIKI TETSUJI
IPC: G10H1/18
Filed: 1993-06-29
Abstract: PURPOSE:To increase the speed of force damping without generating a noise. CONSTITUTION:A waveform generator 21 generates musical sound waveform data according to an indication from a CPU 10, detects the generated musical sound waveform data being at or nearby a zero-cross point. and outputs a zero-cross detection signal DS to an envelope generator 22 and also outputs envelope data ED to a multiplier 23 in synchronism with the generation of the musical sound waveform data, but at the time of force damping, the envelope data ED are attenuated speedily. When the envelope data ED are varied greatly nearby the peak of the musical sound waveform data at the time of the force damping, the actual amplitude variation becomes large and a noise due to the discontinuity of the waveform is generated. When the zero-cross detection signal DS is inputted, the envelope data ED are varied greatly. The zero-cross detection signal DS is outputted nearby the zero-cross point of the musical sound waveform data, so even if the envelope varies greatly, the actual amplitude variation is fine and a noise due to the variation is hardly generated.
