Why do bats emit pulses of ultrasound INSTEAD of continuous waves of ultrasound to navigate?
For the same reason that radar and sonar systems don't transmit continuously.
The information value of these systems comes from interpreting the echo, and
it's very difficult ... virtually impossible ... to receive a low-level signal at the same
frequency while you're transmitting.
That's also the reason why the protocol for the most effective human conversation
involves alternate periods of talking and buttoning it.

What medical technique used sound wave pulses and their reflections to map structures and organs inside the body?
Ultra Sound
What diagnostic technique creates images of deep body structures by redcording the echoes of pulses of sound waves that are above the range of human hearing?
Ultrasound imaging, also known as sonography, is the diagnostic technique that creates images of deep body structures by recording the echoes of pulses of sound waves above the range of human hearing.
Is an imaging technique that records and uses the echoes of pulses of sound waves above the range of human hearing?
The imaging technique you are referring to is likely ultrasound imaging. Ultrasound uses high-frequency sound waves to create images of organs and structures inside the body. It is commonly used in medical diagnostics for its ability to provide real-time images without exposing the patient to harmful radiation.
Why doesnt electric fences kill?
Electric fences are designed to deliver a short, sharp shock that is uncomfortable but not life-threatening to deter animals from crossing the boundary. The current and voltage levels used are typically low and regulated to be safe for animals and humans. Additionally, the electric pulses are intermittent and not continuous, reducing the risk of sustained exposure that could lead to serious harm or death.
What is the rainfall required for pulses?

Does analog signals consist of individual electrical pulses?
No, analog signals do not consist of individual electrical pulses; instead, they represent a continuous range of values. Analog signals vary smoothly over time, reflecting changes in voltage, current, or other physical quantities. This continuous nature allows them to capture nuances in information, unlike digital signals, which are composed of discrete pulses representing binary values.
Analog computer works on the supply of?
electrical pulses but not continuous

Ultra Sound
How do bats use ultrasound to navigate?
They can hear high-frequency sounds that the bats make continually while flying . Bats can determine the direction and distance of objects in the area.This is called echolocation, each species of bat uses echolocation to make its own kind of noises.
What is echlocation?
Echolocation is a type of radar bats use to fly blind. The bats send out pulses of super sonic sound and navigate by the speed of the pulses return from what they bounced ( echoed ) off.
What diagnostic technique creates images of deep body structures by recording the echoes of pulses of sound waves that are above the range of human hearing?
Ultrasound
Why is it necessary for the pulse to be short in ultrasound A- scans?
In ultrasound A-scans, a short pulse duration is crucial to improve resolution and accuracy. Short pulses allow for better differentiation between closely spaced structures, enabling precise measurement of distances within tissues. Additionally, shorter pulses minimize the time the ultrasound signal is emitted, reducing the likelihood of overlapping echoes that can distort the resulting data. Ultimately, this enhances the clarity of the A-scan image, facilitating more accurate diagnostic interpretations.
What creates images of deep body structures by recording the echoes of pulses of sound waves that are above the range of human hearing?
You are refering to ultrasound imaging...Most commonly used in obsteric sonography, which is the imaging of babies within a mothers' womb**Actually the correct medical term for this definition is Ultrasonography. This is the term commonly known as ultrasound or diagnostic ultrasound.**
Why do bats emit short pulses of ultrasound?
Bats are mostly blind so they cry (kind of a screaming/screeching sound), and then they can see the sound waves either bounce off of something that is blocking their way, or just keep going straight in front of them. Then they know weather to turn or go straight.
Why is analogue a series of pulses?
An analogue signal is not a series of pulses. An analogue signal is a continuous signal which is modulated (changed) in some way to carry information. Common modulations for analogue are Amplitude Modulation (AM), and Frequency Modulation, (FM). There are some others but are not needed here.
What is called when a method of using sound instead of eyes?
Echolocation is the method of using sound waves to navigate and perceive one's surroundings, often employed by animals like bats and dolphins. It involves emitting sound pulses and then interpreting the echoes that bounce back to determine the location and features of objects in the environment.
