Switching from the usual base-ten to other number systems (hexadecimal counting, is a base-16 system) Using scientific notation to calculate very large numbers Using logarithms and trigonometric functions directly Working with constants like pi and e at a much higher degree of accuracy Using complex...
4. Frequency setting: When debugging, set a small frequency first, and observe whether the load is running smoothly or not and whether there is any abnormal sound during operation. If so, it is necessary to consider replacing the frequency converter ...
It is extremely easy to create a sine wave with just a few electronic components — a capacitor and an inductor can create the sine wave, and a couple of transistors can amplify the wave into a powerful and simple transmitter schematic. By sending that signal to an antenna, you can ...
you can connect the resistor at the positive end of the string or the negative end, the position doesn't matter because the resistor just needs to be in line with the series, you may even include some wher in between the LED series.Using the...
As is the case when using any scientific instrument, you need to make sure the instrument is in good working order before using it to analyze a sample. Checking the response of the instrument for a known sample verifies that the instrument is properly ca
A more accurate statement would be that our perception of time is proportional to the amount of new and intricate experiences we are observing. If you are practicing a new sport or working on a project that involves a lot of concentration then you perceive time as slower. Since you have ...
the increased input current could cause the primary side components to overheat. If the input voltage is too high, the voltage ratings of the internal capacitors and transistors may be exceeded. Both out-of-spec conditions are likely to allow the output voltage to drift significantly with changes...
If LCD backlight takes more than 3W, then U6 and L1 inductor can have temperature up to 100C degree. In this case you should use additional heat sink to avoid overheating. LVDS cable If you buy standalone board, then you will need to make your own LVDS cable for your LCD panel. We...
A speaker is essentially the final translation machine -- the reverse of the microphone. It takes the electrical signal and translates it back into physical vibrations to create sound waves. When everything is working as it should, the speaker produces nearly the same vibrations that the microphon...
Python is kind to the programmer if there are fewer items than you ask for. For example, if you ask for a[:-2] and a only contains one element, you get an empty list instead of an error. Sometimes you would prefer the error, so you have to be aware that this may happen. Relatio...
