[Detailed description of the invention] This invention especially sounds 4! ! The present invention
relates to a scratch display device which is suitable for two devices i. The sound quality such as
the raw signal can be displayed simply and effectively in the audio equipment 1 and if it is
excellent, it can grasp audio-visual 52 sound quality together with the reproduction sound etc. It
becomes a bribe. The present invention has been made for the purpose of providing a signal
display am suitable for simple and efficient display of sound quality such as the present signal of
the sound device a. ---: 'Tani, Di- One embodiment of the present invention will be described in
detail with reference to the drawings. That is, as shown in the figure, for example, ten devices
(two input terminals to which a signal for display is input from output terminals such as a power
amplifier) are connected to their internal terminals and external ladder resistors (R, R, ) And the
light emitting diodes (LIItDl) and (LjcDm) of the medicine 2 are directly connected as shown in
the figure. When a capacitor (C,) is connected to both ends of the #Ll light emitting diode (LED1),
the polarity is opposite to that of the second light emitting diode (LED2). D o d (Dl) is connected.
Assuming that the input 4 (IN □) (di-applied gI or relatively high-frequency signal), the capacitor
(C □) exhibits a large AC impedance with respect to this signal. So, most of the signals are
practically C Nikonden? The light emitting diode (LIDI) of (01) is added to the inner side of the
light emitting diode (LIDI), and only the detection diode of the light emitting side,% 7'3-1.1(LID1), lights. Conversely, assuming that the signal applied to the input terminal (M1) is a
relatively high frequency signal, C2 should be such that the condenser (C0) exhibits an
impedance close to that of AC ≦ 2 short circuited to this signal. As a result, most of the signal is
substantially added to the light emitting diode (LED, LED) of i: I12, and C2 of the light emitting
diode (LEDI) of the light emitting diode (LEDI) becomes a point XI. Therefore, if all light and ダ イ
オ ー ド 2 light emitting diodes (LID □) and (LmDs) are turned on, it is recommended to set the
first low Mii 1 wave number signal and the high order wave number signal C, respectively.
Because of the phantom S ≦ 2, it is possible to display whether this occasional No. 1 is a signal
of low rock number or a signal of high wave number, that is, this heat @ nobility jt. Moreover,
since each light emitting diode (LICDl) tip and (LJCD) lighting brightness correspond to the size
of the input signal, the level of the C signal can not be shown together with 1% of the above
frequency. Can.
In the above, the resistance (R1) determines the maximum current, ie the maximum brightness,
of each source diode diode, diode (LID1) and (LICD), and the diode (D1) is a% light emitting diode
(LED) And (LkD,) are for logging in which the reverse voltage of 41 does not differ up to the zeta
voltage value. Therefore, according to the present invention as described in detail above, the
circuit configuration can be made extremely simple rather than overturned, and the two light
emitting diodes 6 kept by one storage diode can increase or decrease the M1 number of signals.
It is possible to display large and small effectively, and by using a light emitting diode, it is
possible to operate with a low level signal with almost no power loss of the signal source. It will
be a habit or a habit. The present invention is not limited to the above-described embodiment,
and it goes without saying that various modifications can be made without departing from the
scope of the present invention. A simple 6 yen drawing of the four drawings is a circuit WIdiagram showing a signal table of the present invention, a straight line of a straight line. □), λ
