What is the two level digital puse amplitude modulation?
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.
Why do you get a staircase output in the quantization process of Pulse Code Modulation?
quantisation is the assigning the signal amplitudes to some levels,if amplitude is 4.8 we treat it as 5 and when it is 3.1 the output value is 3 thus we are assigning the amplitude to some reference levels thus corresponds to different amplitudes we get different quantisation output hence we get staircase signal
What is the different between linear and nonlinear pulse code modulation?
The difference between linear and non-linear PCM is LPCM represents sample amplitudes on a linear scale. LPCM specifies that the values stored are proportional to the amplitudes, rather than representing say the logarithm of the amplitude or being related in some other manner. While non-linear each step size may vary in amplitude.
What are the types of pulse modulation?
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
What does the energy of the wave pulse depend on?
The energy of the wave pulse depends on wave length and frequency.
What is pulse amplitude?
escalated annd rapid pulse rate. pounding outside of chest
What are advantages of pulse amplitude modulation?
carry information as well as to generate other pulse modulations.
How is pulse amplitude modulation transmitted?
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).
What effect does warming have on the amplitude of the pulse wave?
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-amplitude modulation?
Explain with diagram the technique Pulse-width modulation?
What type of modulation produces pulses whose duration is proportional to the amplitude of the intelligence signal?
Pulse-Amplitude Modulation
When you were palpating the various pulse points which appeared to have the greatest amplitude or tension?
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.
