What else can I help you with?
What is the difference between directivity index and directivity factor in relation to sound and vibrations?
you dont know..neither I do
How do you obtain the directivity curve of the microphone?
Go in always the same distance with a loudspeaker and a pure tone arround the microphone and measure the microphone's output. You get a damping curve which is the directivity curve.
What is Directivity of the small loop and short dipole has ratio?
The directivity of a small loop antenna is higher than that of a short dipole because the loop antenna is more directional and concentrates radiation in one direction. The ratio can vary depending on the dimensions and configuration of each antenna, but in general, the loop antenna can have a directivity several dB higher than the dipole.
What is the advantage of parabolic reflective antennae?
parabolic reflector having highest directivity.
What are the features of microwave communication?
high directivity high beam width low power transmitter is needed
What is the Application of measurement of directivity and sensitivity using microphone?
The Application of: Directivity- Microphones are made differently. Some microphones pick up sounds only from directly in front of them. Other microphones are pick up sounds well from all directions. The directivity shows all the various sides and angles from which a microphone can pick up sounds. Sensitivity- The sensitivity of a microphone is the gain at which the microphone can pick up sounds. Microphones with high sensitivity can pick up sounds with high gain.
What are directivity and radar cross srction?
Radar cross section is a measure of the electromagnetic energy intercepted and reradiated at the same frequency
What is the formula to calculate directivity?
there is no specific formula to calculate direct cost but direct cost are all those costs which are directly related to production of goods and separately identifiable.
What are the characteristics of a microphone?
1) signal to Noise ratio 2) output level 3) sensitivity 4) frequency response 5) Distortion 6) output Impedance 7) Directivity
What has the author Eleazer Bromberg written?
Eleazer Bromberg has written: 'Mathematical theory of the influence of a dome on the directivity pattern of sound beams, Part 4' -- subject(s): Accessible book
What are the Characteristics of microphone?
1) signal to Noise ratio 2) output level 3) sensitivity 4) frequency response 5) Distortion 6) output Impedance 7) Directivity
How do you determine increased directivity in end fire array?
by calculating the beam width of major lobe of resultant pattern of endfire array.it shoud be sharpaen nd more directive towards axis of array.
