Abstract

PURPOSE:To easily adjust a waveform by setting and resetting a flip-flop by a process or in a device with an external indication, generating a waveform which has a specific period, and inputting its signal to the input terminal of a waveform adjusting circuit. CONSTITUTION:When a switch 2 is turned ON, the processor 3 sets and resets the flip-flop 4 to input the constant-period signal to a switching means 5. Further, the switching means 5 makes the input signal ineffective and the output of the flip-flop 4 effective by the turning-on operation of the switch 2. The waveform adjusting circuit 6 inputs the constant-period signal at this time, so a waveform adjustment measurement point 11 is measured through an oscilloscope and the output terminal of a delay line 9 is adjusted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing device, and particularly to an information processing device having a waveform adjustment circuit that adjusts the waveform of a signal by changing the connection with the output terminal of a delay line. .

[Conventional technology]

Conventionally, this type of information processing device has a means for switching the input of the waveform adjustment circuit to an external signal, and periodically inputs the signal from outside the device, and selects the optimal one among the multiple outputs of the delay line. I selected it and adjusted the waveform.

[Problem to be solved by the invention]

In the conventional information processing apparatus described above, it is necessary to input a waveform of a constant period from the outside in order to select the optimum one among the plurality of output terminals of the delay line and adjust the waveform. For this reason, a measuring device is required when adjusting the waveform, and it also takes time to operate the measuring device, resulting in a disadvantage that the time required for adjustment becomes longer.

[Means to solve the problem]

The information processing device of the present invention includes: a waveform adjustment circuit that adjusts the waveform of a signal by changing the connection with the output terminal of a delay line; a flip-flop 7° that can be set and reset by a processor; It is characterized by comprising a switching means that can be selected as an input to the waveform adjustment circuit, and an instruction means for instructing the processor to set and reset the flip-flop at a constant cycle.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

1 is an information processing device, 2 is a switch (hereinafter referred to as SW),
3 is a processor, 4 is a flip-flop, 5 is a switching means, 6 is a waveform adjustment circuit, 7 and 8 are circuits, 9 is a delay line, 10 is an input signal, and 11 is a waveform adjustment measurement point.

When SW2 is turned on, the processor 3 sets and resets the flip-flop 4, and inputs a constant cycle signal to the switching means 5. Further, the switching means 5 has SW2 set to O.
Since it becomes N, the input signal 10 is made invalid and the output of the flip-flop 4 is made valid.

At this time, a signal with a constant period is input to the waveform adjustment circuit 6, so the waveform adjustment measurement point 11 is measured with an oscilloscope and the output terminal of the delay line 9 is adjusted.

〔Effect of the invention〕

As explained above, in the present invention, a processor within a device sets and resets a flip-flop based on instructions from the outside,
By creating a waveform with a constant period and inputting this signal to the input terminal of the waveform adjustment circuit, the optimum output terminal of the delay line can be easily detected and the waveform can be adjusted without a measuring device when adjusting the waveform.
