Title: Light waveform observing device
Inventor: KUWANO SHIGERU
IPC: G01J9/00
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to observe the signal waveform of several 10 Gb/s without making the signal processing speed high by using light sampling technology by superimposing sampling pulses on a plurality of light signals separated by a light distributing circuit. SOLUTION: The measured input light signal of a high frequency F1 is separated into N pieces (N is an integer of 2 or more) in a light distributing circuit 10. Then, the N pieces of the sampling light pulses, whose timings are deviated separately, are superimposed in optical multiplexers 21-2N. The outputs of these superimposed waveforms are inputted into N pieces of secondary nonlinear mediums 61-6N, and the correlation signal in proportion to the amplitude value of the input signal is outputted. From this output signal, only the correlation- signal component is extracted by optical filters 71-7N and inputted into optical detectors 81-8N. The output signals of the optical detectors 81-8N are amplified to the suitable level in amplifier circuits 91-9N and then converted into the digital signals in AND conversion circuits 101-10N of a sampling frequency fa.  Then, the signal is recorded in memory circuits 111-11N.

Title: Digital audio device
Inventor: ISHIDA MASAYUKI
IPC: G11B20/10
Filed: 1990-10-22
Abstract: PURPOSE:To enable mute time to be minimized by muting signal when the number of codes where an error is detected reaches a specified value within a specified interval when decoding a first code of audio signal and then by turning off the mute when a correction disable of a second code demodulation is 0 in an interval which is multiples of a specified interval. CONSTITUTION:A counter 211 counts an error detection signal C1e when decoding a code C1 at a time t1, resets FF3 when it exceeds m2+(k2/2), sets a mute signal 123a to 0, and then turns on mute. When no error correction is made when demodulating a code C2, a pulse C2e is output. When all signals of a track 1 fail, n1 pulses are output from a decoder 121. Reproduction signal PB1 and PB2 which are input at the time t1 are memorized temporarily and errors are corrected from a time t2 for producing PB1' and PB2'. When error correction of the PB1 is performed by all C2 demodulation, no C2e is output and FF2 stays being set and then input of a strobe clock from a terminal 6 enables an output 123a of an FF3 to be set to 1 and mute to be turned off.
