Analog variable frequency filters require the use of variable passive components. The higher the slope of the filter, the greater the number of needed variable passive components. These elements are ...

Benro’s NE1 Electronic Variable ND Filter Kit goes live on Indiegogo with early bird pricing. We break down features, Dye-LC ...

Without having other variable ND filters for comparison, we can’t make definitive comments on whether the Syrp filter is superior. But we can say that it provides a compact and versatile addition to a ...

Shooting with a ND filter on your lens is like giving your camera a pair of sunglasses—it cuts light without changing the color balance so you can shoot longer exposures with wider apertures in bright ...

The LR2 line reactor series adds seven new frame sizes to match all GS, DURApulse, and WEG drives. The LR2 Series can also be used with a variety of other variable frequency drives (VFD) ...

Across a range of applications, the two most common functions implemented in FPGA-based high-performance signal processing are finite impulse response (FIR) filters and fast Fourier transforms (FFTs).

Delta Optical Thin Film has lifted the application range of variable filters to new levels by introducing a new powerful type of linear variable filter (LVF) Since Delta Optical Thin Film A/S offered ...

New Hoya Variable Density filter in sizes from 52 mm to 82 mm. Each filter uses two polarising layers to control the amount of light that passes through the filter and into the camera lens. They can ...
