Because of transfer functions and the response of the scope
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).
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.
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
The frequency would decrease the gain and increase the output voltage
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
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 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.
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.
Increase the energy in general.
If the frequency increases, the wavelength of the wave will decrease while the energy of the wave will increase.
frequency x wavelength = speedSo, if you increase frequency, the wavelength decreases, and vice versa.
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.
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).
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.
The wavelength is inverse to the frequency, meaning the frequency in this case will increase.
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.
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.
