Adjustable Amplitude High Frequency

13.2 Wave Properties: Speed, Amplitude, Frequency, and …

Teacher Support [BL] For sound, a higher frequency corresponds to a higher pitch while a lower frequency corresponds to a lower pitch. Amplitude corresponds to the loudness of the sound. [BL] [OL] Since sound at all frequencies has the same speed in air, a change in frequency means a change in wavelength. [Figure Support] The same speaker is …

Pseudo-real-time low-pass filter in ECG, self-adjustable to …

Instantaneous cutoff frequency of the filter, as a result of the corresponding length of the filtering window, is shown in subplot c). It can be seen that the low-frequency components of the specific ECG is filtered with a cutoff of 14 Hz, the high-amplitude T-wave is filtered with 26 Hz, and the high-frequency QRS from 100 to 415 Hz.

High Pass Filter Calculator

The slope at which the frequency response drops for increasingly low frequencies is − 20 dB / decade-20 text{dB}/text{decade} − 20 dB / decade.This means that every time the frequency is reduced by a factor of 10, the amplitude is reduced by 20 decibels.This slope is made even steeper if the order of the filter is increased: first-order …

Sliding bearing with adjustable friction properties

The operating point of the adjustable friction bearing is defined by the frequency and voltage amplitude. Limits for the operating point are given by the piezo amplifier; in our case the possible frequency is limited to 20–30 kHz.Placing the resonance frequency within the specifications of the amplifier therefore is another design goal.

controlling vibration frequency and amplitude of a motor

The frequency of the vibrations is directly proportional to the motor's RPM. While the RPM depends on the voltage applied to the motor. The "amplitude" of the vibration as you call it is a function of the frequency hence the drive voltage. Therefore you can't control the frequency and the "amplitude" separately.
