2014年5月29日 · A square wave that remains on the positive plane is a switching DC supply switching between on and off, 0v d.c full voltage d.c. A.c voltage goes beyond 0v to the negative plane you have an alternating current a.c 0v, full voltage positively 0v and negative full voltage back to 0v one complete cycle ac waves can be rectified to be perfectly ...

2021年2月9日 · A sine wave from 2 to 6 volts DC is a 4Vp-p sine wave component plus a 4v DC component. \$\endgroup\$ – K H.

2018年11月7日 · The sine wave is a consequence of the way the AC is produced. When driving a generator you simply cannot directly create DC. Further it's may important to notice that the electrons are not moving like a mass connected to a spring.

2018年4月24日 · If you don’t want the AC signal going directly into your DC power source, you should replace the resistor with an inductor. Then you would have a basic Bias tee. At such a low frequency (600 Hz) your inductor would have to be quite large, however. Something like 1 H. Also, your DC supply should be centered at your mean value: 10 V.

2013年4月5日 · The resulting waveform is an approximation of a triangle wave. It should sound reasonably close to a triangle wave. This signal can be found at the capacitor on pin 6. An image search on "sine converter" will turn up a few circuits that convert a triangle wave to an approximate sine wave. There are a lot of parts in them, though.

2017年5月12日 · Here's how to remove a dc level: - The output DC level can be restored by attaching the resistor (R) to 2.5 volts instead of 0 volts. If you need to connect to a load that might alter the planned DC offset then maybe you will need to add an op-amp buffer.

2020年12月4日 · I connected a DC power supply (set to 706mV) to a 1kohm resistor as this: The semantic is like: However, strange things happen when I use the oscilloscope to view the voltage waveform at point A and B. Below is what is shown on the oscilloscope - cyan wave for point A and yellow for B: As you see the two points are all sine waves.

What you need to do is simply remove the DC offset all together, not supply a negative one. This is known as AC coupling. If you run the output of your square wave generator through series capacitor, it should do what you need. This will however be at the expense of making the square wave less square. An example circuit is shown below for you:

2021年6月21日 · AC stands for Alternating "Current", so you could have a sine wave that is all voltage and no current and it wouldn't fall under the term AC, it would simply be a sine wave of a voltage source. In electrical/physics based science, we tend to treat electricity similar to the flow of water through a system.

2016年12月6日 · I have been trying to find an alt code for the ac/dc symbol, but have not found one or a way to suggest it.
