In the context of filters, cutoff frequency is more often used, but in the context of timing circuitry like this, it's probably better to think in terms of the time constant, $$τ=RC=\frac{1}{2πf_c}$$

Audio Filters Explained: Low-Pass, High-Pass and Beyond

WebPhoton bunching, a feature of classical thermal fields, has been widely exploited to implement ghost imaging. Here we show that spatial photon antibunching can be experimentally observed via low-pass filtering of the intensities of the two thermal light beams from a beamsplitter correlation system. Through suitable choice of the filter … WebThis is because the output port is identical to the input port. Now, add a resistor: simulate this circuit. Note that we now have distinct input and output ports and now we have a 1st order filter. We could have added in inductor instead of a resistor and created a 2nd order filter.

WebIn the case of optical image sampling, as by image sensors in digital cameras, the anti-aliasing filter is also known as an optical low-pass filter (OLPF), blur filter, or AA filter.The mathematics of sampling in two spatial dimensions is similar to the mathematics of time-domain sampling, but the filter implementation technologies are different.

WebA low pass filter is a filter which passes low-frequency signals and blocks, or impedes, high-frequency signals. In other words, low-frequency signals go through much easier and with less resistance and high-frequency signals have a much harder getting through, which is why it's a low pass filter.
