Smaller the pulse width larger is the bandwidth How?

For the Radar Case: The bandwidth of the pulse is the reciprocal of the Pulse Duration (called Pulse Width) as any filtering needs to be able to detection and follow the pulse shape and its edges. The pulse width is the AM modulation to a Fixed Frequency Carrier Frequency and the AM modulation will be greater bandwidth then the Carrier Frequency. As you are attempting to reject receiving other emissions and noise that do not match your own emissions such that your receiver is "match filtered" to your emissions, your receiver bandwidth will be at least the reciprocal of the pulse width but is lightly to be a smaller bandwidth then the reciprocal of the pulse width.


What is the bandwidth of pulse position modulation?

probably (the carrier frequency +- the maximum frequency of the pulse train)/(the carrier frequency) but pulses have a lot of harmonics


What is increased if pulse duration is decreased?

If pulse duration is decreased, the peak power of the pulse is increased. This is because peak power is inversely proportional to pulse duration. So, as the duration of the pulse shortens, the energy is delivered in a shorter time period, resulting in an increase in peak power.


What is the effect of increasing the bits per second in pulse code modulation?

when the bit rate increases bandwidth increases.


A pulse reaches the boundary of a medium in which the speed of the pulse becomes higher. Is the reflection of the pulse the same as for the incident pulse or is it inverted?

same


Why rectangular pulse cannot be sent in ssb modulation?

In theory it can but requires infinite bandwidth. A square wave (or pulse) is a combination of the fundamental frequency and the odd harmonics. If you send a square wave of 1kHz, you need to also be able to send 3kHz, 5kHz, 7kHz, 11kHz ....... etc. Since the bandwidth allowed for most SSB transmissions only allow up to 3kHz bandwidth, all you get is the fundamental of a 1kHz sin wave. On the other hand, if you send a 200Hz tone you can send 200Hz, 600Hz, 1kHz, 1.4Hz, 1.8Hz, 2.2kHz 2.6kHz and this combination will look a lot more like the original 200Hz square wave tone.


Which vicitim requires CPR?

a victim who is unresponsive with no normal breading and no pulse


What is staggered PRI?

Background: PRI = Pulse Rate Interval. PRI is a term used in Radio Frequency (RF) systems. Specifically, Pulse mode RF systems, as apposed to continuous wave (CW) systems. Each pulse has an on period, pulse width (PW), and an off period. PRI is the time from the start of one pulse to the start of the next pulse. For example, if a pulse on time is 10 microseconds (uSec) and the off time is 90 uSec then the PRI is 100 uSec. Answer: A staggered PRI does not have a constant on and off time. The off time varies.


Would the pulse rate be higher or lower after running for 10 minutes?

Higher.


Why are apical pulse usually taken on infants and children?

because infants have higher average pulse rates.


How does pulse width affect wave speed?

In general, pulse width does not directly affect wave speed. The speed of a wave is determined by the medium through which it is propagating and the properties of that medium, rather than the pulse width itself. However, in practical applications, a shorter pulse width may allow for a higher data transmission rate in communication systems, which can indirectly impact the speed of information transfer.


Is it true or false that the faster your heartbeats the slower your pulse will be?

That is false. Your pulse is a measure of your heart rate. The faster your heart beats, the higher (faster) your pulse will be.
