The following figure is a window comparator. Vref is variable from 0 to 5V. The voltage on R2 is guaranteed by an external adder to be always 100mV higher than Vref. Theoretically, when Vref is a cert...
Computers are composed of hardware and software. Hardware is what we can see, such as CPU, memory, motherboard, chipset, graphics card, network card, and sound card. Software is composed of applicatio...
For example, if the sampling rate of the MCU ADC is 200KSPS, is it equal to 200KHZ? Does it mean 200K samples per second? If the crystal oscillator is 11.0592MZ, how to determine whether the clock fre...
