The method goes by the switching method. Making it be possible to see four kinds of the input signals at the same time by switching them at the short period. In addition to the way of introducing here, there is a method which changes the input every period. In case of the method, the changing speed may be low-speed comparatively. The vertical position adjustment is making the direct current rise one above another with the output.(±5V) Because LM747 had the terminal for the offset control, I intended to use this. However, because the voltage change range was small, it wasn't possible to use for the justification. Originally, this terminal is not the terminal for the position adjustment.

The way this time is the way that there is a little impossibility. When adjusting the position, the output voltage, too, has changed. It is possible to use if not making the top or bottom extremely.
The signal vertical (the voltage axis) can be adjusted with VR1. But, that the oscilloscope to use can be displayed in the direct current is the condition.
It is the circuit which does the switch of the four input signals. As the IC, it is using the thing for the switching of the analog signal. Because the power supply voltage of this IC is using ±5 V, it can handle the signal in the ±5 V range as the signal.
According to the condition of the switch control line, the input signal of CH1-CH4 appears in the output.
As for the figure on the left, the changing frequency is in the condition which isn't too fast to the frequency of the input signal. Because it is, the output signal (red) becomes the dotted line. Actually, if the input signal is lower sufficiently than the switching frequency, you can see the continued line.
Because it wasn't possible to use the offset terminal, as the input amplifier, the operational amplifier can use TL084 with the housing of the four in the 1 package. Because pin connections are different, the pattern must be reformed.
It is adjusting the mu factor of the amplifier with VR2. When VR2 is the smallest (the condition which connected the output of the amplifier and the negative input...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
