DETAILED DESCRIPTION OF THE INVENTION The present invention is a digital conversion
circuit for audio signals, and it is possible to change the boldness of the Wk output rich pattern
on the D'jlm IC as the O @ When it comes to%, it is possible to change the color by its high and
low levels and to provide% O% that can be set. Following, * 1 device 11 m11 l about 1 self and-de
IJJfh. 2。 · In 1111ll, after the terminal aK is added and the audio signal is amplified by the
amplifier 1, if it is stored by the filter paths 2, 8.4 and 6, the low band, mid band 1. It is separated
into four of the mid band 2 and the high band, and each is integrated by the integrating circuit 6.
Since this integral signal 4g differs in amplitude depending on the strength, the conversion
circuit 7 changes the frequency of the pulse by this amplitude. 8 flights Il! Excellent, common to
the converter circuit Kli 絖 'sn. An integral ** eo output signal is shown as an example of the

promoting Dna: ff and tc1 o discharge. R1 and R2 become cloudy with the resistance of the

output signal of the Jl oscillator 8, H to the output signal of 信号 2111A point of the monostable
multivibrator MMV1) Has changed to a constant pulse 21st! It is a wave form diagram which
each shows the final output signal of point lB. H) When a signal as shown by K arrives at the
terminal of 纂 2 (2), the signal is small at the beginning, so the internal resistance & of the
transistor Tr + is large, so the time constant is large and the pulse width is wide ( However, since
the signal becomes important next ll, the pulse width becomes narrow. As described above, the
four output signals shown in FIG. 1 are taken out, for example, the output signal of the filter
circuit 2 is red, the circuit 3tIIII color, and the lit] flil path 4 is the back color, If it is decided that
the circuit 61P is white, the color with the largest number of t pulses is lighted by comparing
four signals in a certain W # terminal, and the size thereof is determined by the number of pulses
of its 1111111R. It is a town hall that projects a pattern synchronized with.
