WebSep 24, 2024 · 0. Regarding the AHB/APB question, this is best explained with a look at the Clock Tree. AHB and APB are not the same bus. The AHB has memory and core, the APB has peripherals. Energy wise these might not have the same speed. A special case in ST chips is that the peripherals, including the timers registers, are clocked at PCLK1 and the … WebThe so-called dither noise is summed into the lower W+1 bits of the PA output word to linearize the truncation operation.

The Nyquist Criteria states that the clock frequency (sample rate) must be at least twice the output frequency. Practical limitations restrict the actual highest output frequency to about 1/3 the clock frequency. Figure 5 shows the output of a DAC in a DDS . Page 4 of 9

…[O]ne of the earliest [applications] of dither came in World War II. Airplane bombers used mechanical computers to perform navigation and bomb trajectory calculations. Curiously, these computers (boxes filled with hundreds of gears and cogs) performed more accurately when flying on board the aircraft, and less well on ground. Engineers realized that the vibration from the aircraft reduced the error from sticky moving parts. Instead of moving in short jerks, they move… WebMar 19, 2013 · Spread spectrum clock generation (SSCG) or “dithering” (modulating the clock frequency), has been around for a long while, even before the PC and printer …
