Web5 hours ago · f = ΔPhase × fMCLK/2π 该如何理解上述的核心思想，我们来举一个简单的例子：先假设 DDS 有一个固定时钟，MCLK，为 36Mhz，那么每个脉冲的周期为 27.78ns。 有一个正弦波的 “相位-幅度” 表，具有足够细密的相位步长，0.01°；那么一个完整的正弦波表就需要 36000 个点。 WebThe companding standard employed in the United States and Japan is the μ-Law and allows 14 bits bits of dynamic range. The European companding standard is A-Law and allows 13 bits of dynamic range. The μ-Law and A-Law formats encode data into 8-bit code elements with MSB alignment. Companded data is always 8 bits wide.
WebJul 27, 2024 · 输出正弦波频率为： fOUT＝M（fMCLK/228） （1） 其中，M为频率控制字，由外部编程给定，其范围为0≤M≤228－1。 VDD引脚为AD9833的模拟部分和数字部分供电，供电电压为2.3V－5.5V。 AD9833内部 数字电路 工作电压为2.5V，其板上的电压调节器可以从VDD产生2.5V稳定电压，注意：若VDD小于等于2.7V，引脚CAP/2.5V应直接连接 … WebAug 4, 2011 · First of all, DDS output signal of frequency of Fmclk/2, where Fmclk is master clock of the DDS, is very tricky. Why? Because, for generating signal of Fmclk/2 frequency, DDS reads from the sin lookup table only two samples - one from positive and one from negative part. In case of AD9834 there are overall of 2^12=4096 samples in lookup table.

При Fmclk с честота 75 MHz от опорния генератор, максималната изходна честота на DDS AD9834 е около Fmclk/2 или Fmax = 75/2 = 37,500 MHz, но имайки предвид параметрите на изходния сигнал, би било добре изходната честота да не …
WebSo, I recently made a new “canon” warden for myself that I chose not to do the ritual. I played a male mage warden that romanced Morrigan. I killed Flemeth for her and made it clear I’d do anything to free her from Flemeth’s machinations. It’s pretty clear the ritual is Flemeth’s design. Morrigan admits as much herself.
