When playing a 10khz sine wave on a ce, there is a "pop" noise when adjusting the volume. Later, it was found that the noise occurs every time the volume changes from ffff by 1024 units. In other word...
I am learning PWM current tracking recently. There is a triangle wave comparison method PWM tracking algorithm commonly used in APF. My program idea is to set the 2812 counter to increase or decrease ...
With the development of ultra-deep submicron technology, IC design capabilities and process capabilities have been greatly improved. The use of SoC (System on Chip) to integrate microprocessors, IP co...
318863 1. Topic: When designing PCB, the power pin of the chip usually needs to add 0.1uF decoupling capacitor. The decoupling capacitor is placed near the pin, and a via is made near the power layer ...
Do the CPU internal registers have capacity? This question may seem naive, but I have been confused by many collection or assembly tutorials. For example, when someone mentioned the 8086 16-bit regist...
Designers use PSpice primarily to simulate analog circuits. However, it can also be used to simulate digital filters. The main components in a digital filter are delay elements, adders, and multipl...[Details]
