4. (Chemistry) chem. a. an organic chemical compound related to another by substitution of hydrogen atoms with alkyl groups: toluene is an analogue of benzene. b. an organic compound that is similar in structure to another organic compound: thiols are sulphur analogues of alcohols.
Yes since your heart rate fluctuates based upon your activity level. Resting heart rate varies greatly from your active heart rate. The P wave and the QRS complex represent depolarization of the atrial and ventricular muscle respectively. Why does the QRS complex have the larger amplitude? The QRS complex correlates with the action needed to push blood back out away from the heart that requires higher pressure. Heart rate was calculated based upon the peak-to-peak interval of the R waves.
There are two main properties of a regular vibration-the amplitude and the frequency-which affect the way it sounds. Amplitude is the size of the vibration, and this determines how loud the sound is. We have already seen that larger vibrations make a louder sound.Amplitude is important when balancing and controlling the loudness of sounds, such as with the volume control on your CD player.It is also the origin of the word amplifier, a device which increases the amplitude of a waveform. Frequency is the speed of the vibration, and this determines the pitch of the sound.It is only useful or meaningful for musical sounds, where there is a strongly regular waveform.t is also the origin of the word amplifier, a device which increases the amplitude of a waveform.
