The exact frequency response of the filter depends on the filter design. The filter is sometimes called a high-cut filter, or … Meer weergeven Examples of low-pass filters occur in acoustics, optics and electronics. A stiff physical barrier tends to reflect higher sound frequencies, and so acts as an acoustic low-pass filter for transmitting sound. … Meer weergeven The time response of a low-pass filter is found by solving the response to the simple low-pass RC filter. Using Kirchhoff's Laws we arrive at the differential … Meer weergeven A discrete difference equation is easily obtained by sampling the step input response above at regular intervals of $${\displaystyle nT}$$ where $${\displaystyle n=0,1,...}$$ and $${\displaystyle T}$$ is the time between samples. … Meer weergeven There are many different types of filter circuits, with different responses to changing frequency.
