The rhythmical throbbing of arteries produced by the regular contractions of the heart, especially as palpated at the wrist or in the neck
The carotid pulse is typically considered to have the greatest amplitude or tension when palpating different pulse points on the body. This pulse is able to be felt more easily due to its proximity to the heart and larger blood vessels.
As you go farther away from the heart the arteries differentiate into smaller arterioles. As a result the elastic recoil of the arterial wall lessens and the perceivable intensity of the pulse also lessens.Hope this answered your question.
Amplitude. As the amplitude of the sound wave increases, the sound becomes louder.
The amplitude of a sound corresponds to its loudness so an increase in amplitude will correspond to a louder sound.
amplitude The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound.

carry information as well as to generate other pulse modulations.
Generally pulse amplitude modulation (PAM) is trasmitted as a series of DC levels and are mostly used in wired trasmissions (DC is not effective wirelessly).
Warming can increase the amplitude of the pulse wave by causing vasodilation, which leads to increased blood flow and pressure in the arteries. This can result in a stronger pulse wave that is more noticeable and easier to detect.
Explain with diagram the technique Pulse-width modulation?
Pulse-Amplitude Modulation
The carotid pulse is typically considered to have the greatest amplitude or tension when palpating different pulse points on the body. This pulse is able to be felt more easily due to its proximity to the heart and larger blood vessels.
PAM-pulse Amplitude Modulation It encodes information in the amplitude of a sequence of signal pulses. PPM-Pulse Position modulation PWM-Pulse Width Modulation.It results in variation of average waveform.
In Pulse Amplitude Modulation, amplitude of pulse varies with signal. Theoretically in analog modulation there infinite levels of amplitudes or continuous amplitude. Two level PAM is digital modulation where only 2 number of levels are there. Thus signal is quantized to two discrete levels.
In pulse amplitude modulation (PAM), you send a single pulse of a certain height (amplitude) that represents the value of the sampled signal at that time. With pulse code modulation (PCM), you take the same sampled value, but now represent that value by N bits, where N is the number of quantized regions. Why send a whole bunch of bits instead of just a single pulse? Because PCM performs better in situations of higher noise (AWGN).
