What else can I help you with?
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).
What happens to waveform on oscilloscope when we increase the voltage level from function generator?
When the voltage level from the function generator is increased, the waveform displayed on the oscilloscope will rise in amplitude, appearing taller on the vertical axis. The shape of the waveform remains the same, whether it's a sine, square, or triangle wave, but the peaks and troughs will be more pronounced. Additionally, if the vertical scale on the oscilloscope is not adjusted, the waveform may clip if the voltage exceeds the oscilloscope's maximum input range.
What the function of time base in an oscilloscope?
The time base of an oscilloscope is used to increase or decrease the time per division value on the Y-axis ranging from few tens of seconds to micro seconds to nanoseconds used for microwave signals.If you increase the time base of an oscilloscope lesser and lesser part of the signal will be present in one division of the Y-axis. Setting the time base to a proper value will enable you to see high frequency signals clearly otherwise each cycle of the signal would be indistinguishable from the other huehue
What is the effect of low frequency on the voltage?
The frequency would decrease the gain and increase the output voltage
Why high frequency signal is more affected by noise compare to low frquency signal?
AS FREQUENCY INCREASE THE BANDWIDTH INCREASE. AS WE KNOW NOISE HAVE LARGER BANDWIDTH. SO ITS AFFECT HIGH FREQUENCY SIGNAL. BUT LOW FREQUENCY SIGNAL HAVE LOW BANDWIDTH SO IT IS LESS AFFECTED BY NOISE. ALSO WE KNOW QUALITY FACTOR= CUTOFF FREQUENCY / BANDWIDTH. SO AS FREQUENCY INCREASE B.W. INCREASE SO QUALITY DEGRADE. CUTOFF FREQUNCY AND THE TERM FREQUENCY (USED HERE) IS DIFFERENT. CUTTOFF FREQUNCY IS USED IN FILTER. PRABIR KUMAR SETHY prabirsethy.05@gmail.com
How does the sampling oscilloscope increase the appearent frequency response of an osciloscope?
A: A sampling scope is not real time scope but rather a hi frequency rate of sampling which benefit the observer
The Doppler effect of a passing siren results from an apparent change in?
The Doppler effect of a passing siren results from an apparent change in frequency as the source of the sound moves relative to the observer. This change causes the pitch of the sound to either increase (higher frequency) as the source approaches or decrease (lower frequency) as the source moves away.
How do you make an oscilloscope trace brighter?
To make an oscilloscope trace brighter, you can adjust the vertical sensitivity (volts per division) to a lower setting, which increases the amplitude of the displayed signal. Additionally, increase the intensity or brightness setting on the oscilloscope if available. Lastly, ensure the oscilloscope is properly calibrated and that the probe is correctly connected to minimize signal loss.
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 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.
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.
