You see how long it takes for each signal and find the average. Example: 1st: 1second 2nd: 3seconds 3rd: 2seconds. So add all and divide by how many terms (3). 1+3+2=6 6/3= 2. The frequency is 2units. I hope this is right.........
the low frequency signal which is nothing but the message signalNeither. The envelope will be that of the difference beat frequency. To get the envelope to follow the low frequency input signal you need to mix (multiply) the two signals, not add them.
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 you sample at more than the Nyquist frequency (one half the signal frequency) you introduce an aliasing distortion, seen as sub harmonics.
modulating signal is the message to be carried by the carrier signal.
True.
The frequency domain of a voice signal is normally continuous because voice is a nonperiodic signal.
Yes. The Fourier transform of a signal to the frequency domain will give rise to a graph that has energy (is greater than zero) at only the base frequency and its harmonics.
repetition rate of signal
frequency meter is used to measure the frequency of unknown frequency signal.
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.
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.
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.

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.
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.
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.
