WebDec 13, 2024 · In particular, a rough approximation is that 70% of the power is concentrated from DC up to the knee frequency, which is equal to approximately one-third of the inverse of the signal rise/fall time (from 10% to 90%). Power spectral density of an example digital signal. All this means that, when the rise time is faster, EMI is more intense. WebApr 23, 2024 · We'll assume you have a high-speed clock (e.g., 10 - 50 MHz) available. We replace the charge pump with a binary up/down counter, replace the VCO with a DDS, and instead of relying on analog pulse widths, we sample the phase of the DDS at the rising and falling edges of the input pulses.
