How to increase radar range?

The maximum distance at which a radar set is ordinarily effective in detecting objects can be increase by lowering the pulse frequency, raising the peak power of the transmitter, narrow the beam with and increasing the pulse duration


What is the effect on voltage gain in a common emitter amplifier when the decoupling capacitor is removed?

The emitter bypass capacitor, in a typical common emitter configuration, increases gain as a function of frequency, making a high pass filter. Removing the capacitor will remove the gain component due to frequency, and the amplifier will degrade to its DC characteristics.


Up to which frequency does the gain of an antenna increase as the frequency increases?

In general, an antenna is "cut" or "built" for one frequency, or for a band of frequencies centering on one particular frequency. This antenna will respond to all frequencies, but will only exhibit "maximum" gain at one frequency. Frequencies higher or lower will not be received quite as well, and the farther from the "tuned" or "center" frequency the signal is, the less gain the antenna will provide on that frequency. As we work with an omnidirectional antenna, we can "tinker" with it a bit in an attempt to get it to work with a broader range of frequencies, but as we broaden the usable spectrum over which it will work, we will see less gain on the "center" frequency. If you're getting the idea that tuning an antenna involves trade-offs, you're getting the right picture. No improvements are possible without "cost" in another part of the operating spectrum. If we move to a directional TV antenna like, say, one of those antennas (not the dish) that still can be seen on some rooftops, we see what is basically a modified log periodic antenna. This antenna will generally be "pointed" or "aimed" in the general direction of the transmission antenna of the station(s) for which reception is desired. Stations with broadcast antennas to the side or the rear of this antenna won't be "seen" as the antenna is highly directional. Having said all that to get you up to speed on some fundamental concepts of the antenna, as we move up the frequency spectrum (starting "low"), the gain of the antenna will increase until we reach the "center" or the "tuned" frequency for that antenna. After that, increasing the frequency will result in signals with increasingly lower gain.


What the need for amplifiers used in biomedical applications?

Amplifier is a electronic device. It is a combination of transistors & FET. To give an input signal to an amplifier, it does not change the value of frequency & waveshape .It increase only the value of amplitude.


What is the function of emitter bypass capacitor in common emitter amplifier?

The emitter bypass capacitor in a common emitter amplifier will have less resistance as the frequency increases. Since gain in this configuration is collector resistance divided by emitter resistance (within limits of hFe), the gain will thus increase for higher frequencies, making this into a high pass filter.

How do you increase a waves frequency?

Increase the energy in general.


Which one will be affected if the frequency increase?

If the frequency increases, the wavelength of the wave will decrease while the energy of the wave will increase.


As the frequency of a wave of constant speed is increased does the wavelength increase or decrease?

frequency x wavelength = speedSo, if you increase frequency, the wavelength decreases, and vice versa.


If the period of wave decreases its frequency must?

increase. The frequency of a wave is inversely proportional to its period, meaning that as the period decreases, the frequency increases. The relationship between frequency and period is given by the formula: frequency = 1 / period.


Is The carrier frequency is usually lower than the modulating frequency?

when the frequency is low , energy will be obviously low. To increase the energy of the signal we need to increase the frequency. This is achieved by multiplying the message signal with the carrier signal (with high frequency).


If the period of a wave decreases its frequency must?

Period and frequency are inverse to each other, as period increases frequency decreases. So, to answer this question as the period of the wave decreases its frequency must increase.


When wavelength decreases does the frequency increase or decrease?

The wavelength is inverse to the frequency, meaning the frequency in this case will increase.


What happens to the wavelength the if we increase the frequency of vibration?

Provided the speed of the wave remains constant, as we increase the frequency of wave then wavelength decreases. Because frequency and wavelength are inversely related.


What difference will you hear in a sound there is increase In the frequency?

An increase in frequency will result in a higher pitch sound. The sound will be perceived as being "higher" or "squeakier" compared to a lower frequency sound.


When a wave source moves toward a receiver does the receiver encounter increase in frequency wave speed or both?

Increase in frequency only.


What would happen to the wave length if you could increase the frequency of a periodic wave?

If you increase the frequency of a periodic wave, the wavelength would decrease. This is because wavelength and frequency are inversely proportional in a wave: as frequency goes up, wavelength goes down.
