Question

急求英文翻译！！！

line structure in the spectrum of the
recursive CORDIC, and the phase error
correction is not applied to suppress phase
error artifacts but rather to complete the
phase rotation left incomplete due to the
residual phase term in the angle accumulator.
This is a very different DDS!
IMPLEMENTATION
As a practical note, there are truncating
quantizers between the AGC multipliers
and the feedback delay element registers.
As such, the truncation error circulates
in the registers and contributes an
undesired dc component to the complex
sinusoid output. This dc component can
(and should) be suppressed by using a
sigma delta-based dc cancellation loop
between the AGC multipliers and the
feedback delay elements [6].
CONCLUSIONS
We modified the traditional recursive
DDS complex oscillator structure to a
tangent/cosine configuration. The tan(θ)
computations were implemented by
CORDIC rotations avoiding the need for
multiply operations. To minimize output
phase angle error, we applied a post-
CORDIC clean-up angle rotation. Finally,
we stabilized the DDS output amplitude
by an AGC loop. The phase-noise performance
of the DDS is quite remarkable
and we invite you, the reader, to take a
careful look at its structure.
