An array of such actuators, each serving as a high frequency mechanical filter, could be used for parallel signal processing in telecommunications.
Pulse-Doppler signal processing separates reflected signals into a number of frequency filters.
The coincidental formation of an audio frequency filter is also beneficial in that noise is reduced.
The system uses a sliding frequency guiding filter to regulate the speed of the soliton waves.
Conversely, the wafer-thin ears of many bats act as sound frequency filters allowing all but the most ultrasonic frequencies to pass right through.
Very low frequency filters are often designed with crystals to overcome this problem.
The amount of movement or sensor travel is larger that the higher frequency filter vibrating types.
Lorq cut the frequency filter till Caliban was sliding down the gravitational distortion of the mountain itself.
We thus consider the effect of passing a turbulence signal through a frequency filter before the usual squaring and averaging.
The wavelength of the lowest frequency filter that will be used to analyze the data is usually defined as the sampling length.
