The combination of NIKKOR lenses, a high pixel-count CMOS image sensor unit which does not include an optical low-pass filter
, and an effective pixel count of 24.
The ideal low-pass filter
X is associated with the characteristic function of an interval centered at k = 0, so [?
Its APS-C sensor is designed without an optical low-pass filter
, which allows users to take full advantage of its 24.
Next, we will elaborate the four vital components of DDC: FPGA realization of digitally controlled oscillator, CIC filter, HBF and low-pass filter
This paper introduces an implementation form for the digital low-pass filter
, which achieves a good precision of output evaluation, while keeping low the computational effort.
1 effective megapixels, and the EXPEED 3 image-processing engine optimized for high-performance without an optical low-pass filter
I also did my usual run of frequency-response measurements, and found that the unit was essentially as good as my other subs down to the above-noted 35 Hz, provided that the low-pass filter
The on-chip audio processor alleviates the need for an external low-pass filter
in most cases.
2-million pixels, a super high-speed AF CMOS sensor with no low-pass filter
, the latest EXPEED 4A image-processing engine, and support for a broad range of sensitivities, from ISO 200 to 12800, the S2 is capable of capturing sharp and clear images exhibiting very little noise, even with shooting in dark surroundings
The optional 8-pole i500 analog low-pass filter
daughterboard provides very accurate anti-aliased data at low cost.
As with the earlier version, that device is still rated at 150 watts (with a soft-clipping feature to minimize harmonic artifacts during high-output use), and it employs a low-pass filter
that can be varied from 30 Hz to 90 Hz.
