What else can I help you with?
Why the linear combination of a low frequency intelligence signal and a high frequency carrier signal is not effective as a radio transmission?
to shift the frequency of information signal ,at the frequency domain to a higher frequency ...so the information can be transmitted to the receiver.
Is the frequency domain plot of a voice signal discrete or continuous?
The frequency domain of a voice signal is normally continuous because voice is a nonperiodic signal.
What is meant by a low pass signal?
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
Why is the frequency spectrum of a discrete signal repetitions of the spectrum of the analog signal?
The analog signal is converted to discrete signal. Even after the conversion, the frequency of the actual signal still remains the same. If the frequency of the discrete signal is different from the analog signal, the reconstructed signal would be different again. This is not what we expect. So base spectrum for similar signals have same frequencies, whether they are discrete or analog. Why do the repetitions occur? The original analog signal is multiplied with a dirac pattern. The base frequency is then shifted to the places, where diracs are available. So long the diracs keep repeating, the base frequency do repeats. Hope you are convinced with my answer
What does radar measures?
It measures the time it takes for a radio signal of a particular frequency to travel to a target and back. It also measures the strength of the signal when it returns. Based on the travel time of the signal, the radar can measure the distance of the target. Once the radar receives the 2nd signal, it can calculate the velocity of the target. The strength of the signal can be used to determine the size of the target.
What is frequency meter?
frequency meter is used to measure the frequency of unknown frequency signal.
How can one accurately measure the frequency in hertz (Hz) of a given signal or waveform?
To accurately measure the frequency in hertz (Hz) of a signal or waveform, one can use an oscilloscope or a frequency counter. These devices can analyze the signal and provide a numerical value for its frequency in hertz.
What instrument is used to measuring Frequency?
An oscilloscope or a frequency counter can be used to measure frequency. Oscilloscopes display the waveform of a signal and can measure its frequency, while frequency counters directly count the number of signal cycles per second to determine frequency.
How can I measure frequency with a multimeter?
To measure frequency with a multimeter, set the multimeter to the frequency measurement mode. Connect the multimeter's probes to the circuit or signal you want to measure. The multimeter will display the frequency in hertz (Hz) on its screen.
How to measure frequency with a multimeter?
To measure frequency with a multimeter, set the multimeter to the frequency measurement mode. Connect the multimeter's probes to the circuit or signal you want to measure. The multimeter will display the frequency in hertz (Hz) on its screen.
Conversion of decibel into frequency?
Decibels (dB) and frequency are different units of measurement that measure different things. Decibels measure the intensity or level of a sound or signal, while frequency measures the number of cycles of a wave that occur in a second. There is no direct conversion of decibels into frequency because they measure different aspects of a signal.
How can I measure hertz with a multimeter?
To measure hertz with a multimeter, set the multimeter to the frequency measurement mode and connect the probes to the source of the signal. The multimeter will display the frequency in hertz.
How can a multimeter be used to accurately measure frequency?
A multimeter can accurately measure frequency by selecting the frequency measurement function on the device, connecting the multimeter to the circuit or signal being tested, and reading the displayed frequency value on the multimeter's screen.
What is the procedure for measuring frequency in hertz using a multimeter?
To measure frequency in hertz using a multimeter, set the multimeter to the frequency measurement mode. Connect the multimeter's probes to the circuit or signal you want to measure. The multimeter will display the frequency in hertz on its screen.
Define modulation and modulation index?
a measure of the degree of frequency modulation expressed numerically for a pure tone modulation as the ratio of the frequency deviation to the frequency of the modulating signal.
How to measure hertz on a multimeter?
To measure hertz on a multimeter, set the dial to the frequency measurement setting (usually denoted by "Hz"). Connect the multimeter leads to the source of the frequency signal. The multimeter will then display the frequency in hertz on its screen.
How to check frequency with a multimeter?
To check frequency with a multimeter, set the multimeter to the frequency measurement mode. Connect the probes to the circuit or signal you want to measure. The multimeter will display the frequency in hertz (Hz) on the screen.
