If you meant power, then the answer is a trivial first-order low pass filter or high pass filter.
22.
Once this signal passes through a low pass filter, the higher frequency component is removed, leaving just the original message.
23.
The basic sample sound was then processed by a simple digital low pass filter, and then fed into the digital amplifier.
24.
One solution would be to overclock the conversion elements, introduce a digital filter and follow them with an acoustical low pass filter.
25.
Analog phase locked loops are generally built with an analog phase detector, low pass filter and VCO placed in a negative feedback configuration.
26.
At the output of the amplifier the audio is separated from the RF signal by the low pass filter and is applied to the earphone.
27.
The Sony ?230's anti-dust system is a charge protection coating on a low pass filter and image-sensor shift mechanism.
28.
The Sony ?290's anti-dust system is a charge protection coating on a low pass filter and image-sensor shift mechanism.
29.
This decomposition is repeated to further increase the frequency resolution and the approximation coefficients decomposed with high and low pass filters and then down-sampled.
30.
Butterworth showed that a low pass filter could be designed whose cutoff frequency was normalized to 1 radian per second and whose frequency response ( gain ) was
