The figure below is a basic block diagram of phase-sensitive detection. I just don’t understand what technical requirements are there for the cutoff frequency of the integrator, which is the low-pass ...
I have been working for some years, but it seems that my working methods are not right and I always stay at the rookie stage.
There are many people who have helped me at work, and I would like to desc...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into one chip. In general, a c...[Details]
China's new energy vehicles are in a transition period from research and development to real industrial development. In 2012, with the intensive launch of new energy vehicle policy planning, the de...[Details]
