While the ideal low-pass filter
is characterized solely by its bandwidth, our HDAF approximation is controlled by two parameters n and [sigma].
In DSPBuilder, the model of FIR low-pass filter
is shown in Figure 9.
Because the low-pass filter
has unitary gain, the filter coefficients have the following property:
In most cases, built-in high-pass and low-pass filters
are not needed in a subwoofer, because the owner will be making use of an outboard crossover of some kind (usually contained within a surround preamp or surround receiver).
I initially set the Hsu low-pass filter
to the bypass position.

4-million pixels, a super high-speed AF CMOS sensor with no low-pass filter
, and the latest EXPEED 4A image-processing engine, the NIKON 1 J4 offers superior image quality.
Semtech's proprietary digital low-pass filter
samples the PWM dimming signal to extract the duty cycle information and maps this into the current setting DACs.

In common with many digital cameras, the original Cyber-shot RX1 camera features a multi-segment optical low-pass filter
(OLPF) in front of the sensor to suppress unwanted moire and color artifacts.

In addition to its infrared proximity sensor and ambient light sensor, the chip contains a digital low-pass filter
that removes florescent light flicker, a 12 bit A/D converter, DSP, temperature compensation circuit, I2C interface, oscillator and a driver for an infrared emitter.
