Why to have a filter before and after a low noise amplifier?
To cut off unwanted frequencies, unwanted frequencies are called noise.
Need of pre-emphasis and de-emphasis circuits in digital communication?
de-emphasis is the complement of pre-emphasis, in the antinoise system called emphasis. Emphasis is a system process designed to decrease, (within a band of frequencies), the magnitude of some (usually higher) frequencies with respect to the magnitude of other (usually lower) frequencies in order to improve the overall signal-to-noise ratio by minimizing the adverse effects of such phenomena as attenuation differences or saturation of recording media in subsequent parts of the system.Special time constants dictate the frequency response curve, from which one can calculate the cutoff frequency.
Why RC coupled amplifier is called audio amplifier?
Because radio control relies on different frequencies. Since frequencies are involved in the process, an audio amplifier can be used to amplify alternating currents (currents that change), and it does the same job.
What is an ultra wideband antenna?
Antennas can be tuned for specific frequencies to increase their gain. These types of antenna are sometimes referred to as narrowband. An ultra wideband antenna works for a lot of frequencies around what is called a center frequency. For example, if you had a narrowband antenna centered around 10 megahertz it might work for frequencies from 9 to 11 megahertz for example. If it were wide band it might go from 5 to 15 megahertz, and so forth. The bands are clustered around specific center frequencies for different applications.
How long is a cord?
There is no unit of measure called a cord.
A measure of the space that matter occupies?
That is called the volume.
What is the measure of the space of a solid figure occupies called?
Its volume.
What is the measure of the space a solid figure occupies is called?
The measure of the amount of space a solid figure is Volume
What is the measure of the amount of space a solid figure occupies called?
The measure of the amount of space a solid figure is Volume
What is the term for the unit that measure wave frequencies?
The unit of frequency is "Hertz", abbreviated "Hz". Also called "cycles". Also called "per second".
What is anything that has mass and occupies space?
Matter
Frequencies to low for people to hear are called what?
"Subaudible" frequencies.
What is measured in units called milliliters and cubic centimeters?
Milliliters and cubic centimeters are units the measure volume. Volume refers to the space that an object or substance occupies.
What refers to the amount of space a drug occupies?
The amount of space anything occupies is normally called its "volume".
Can A standing wave can only occur at natural frequencies?
A standing wave can occur only at specific frequencies that are called natural frequencies.
What is the frequency of a sound a measure of?
The basic unit of a frequency is called Hertz. One Hz is one cycle per second. This applies to frequencies such as sound, radio, and light.
What are elecromagnetic waves with the highest frequencies called?
gamma rays. they have the shortesst wawvelengths and the highest frequencies.
