Whether it is a solid capacitor or an electrolytic capacitor, their main function is to filter out clutter, so as long as the capacity reaches a certain value, as long as the capacitor The quality of its components can also ensure the stable operation of the motherboard. At this point, the electrolytic capacitor can also do this. When the solid capacitor is at 105 degrees Celsius, it …
Judging the quality of DAC: ... To achieve this we can either connect a capacitor across the output, or I would recommend to add a 2nd order low pass filter to PWM output. Low pass filter or capacitor acts as an averaging circuit, takes the average of the PWM hence give a smooth analog signal in output. Data, PWM and Sine function used here: I want to generate a Sine …
