What happens when you add two sine waves?

The sum of two sine waves with the same frequency is again a sine wave with frequency . This is used for the analysis of linear electrical networks excited by sinusoidal sources with the frequency .

Can you multiply two sine functions?

When you multiply two sine waves, you end up with the sum and difference frequencies. So if the input frequency is 600KHz and the local oscillator frequency is 1055kHz, you end up with 455kHz and 1655kHz.

What is the relationship between the frequency and period of a sine wave?

Frequency, f, is how many cycles of an oscillation occur per second and is measured in cycles per second or hertz (Hz). The period of a wave, T, is the amount of time it takes a wave to vibrate one full cycle. These two terms are inversely proportional to each other: f = 1/T and T = 1/f.

What happens when you multiply two frequencies?

Mixer can be called as a ‘Frequency converter’ or ‘Frequency Translater’. If you multiply two signals with different frequency, it produce a composite signal with the two frequencies, one of them is the sum of the two input frequencies and the other is the differences of the two frequencies. It is law of physics.

What happens when you add two sine waves of equal frequency equal amplitude and opposite phase?

If two sinusoidal waves having the same frequency (wavelength) and the same amplitude are travelling in opposite directions in the same medium then, using superposition, the net displacement of the medium is the sum of the two waves.

Why is frequency inversely proportional to period?

We know that frequency and time period are the inversely proportional quantities form the definition of the frequency and time period. The frequency and period are inverse functions because when the frequency is high, then the time period is low, or when the time period is low, then the frequency is increased.
