It can have near enough any amplitude.
It depends on the usage. A proportional counter operates in the linear region, meaning that the amplitude of the pulse is proportional to the energy of the captured ionizing event. Integrating the pulses yields an estimate of the total energy in the field, which is related to dose rate. A geiger counter, on the other hand, operates in the avalanch region, which means that every ionizing event yields the same amplitude pulse. You lose the ability to estimate dose rate, but you gain sensitivity. The advantage is the ability to quantify, though not qualify, contamination levels.
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).
Explain with diagram the technique Pulse-width modulation?
Pulse-Amplitude Modulation
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).
Yes, the QRS complex and the pulse wave are directly connected. The amplitude of these, combined with the first heart beat sound, make up systolic pressure.
