a)Draw a sine wave and point out the Amplitude, Peak Amplitude, Peak-to-Peak Amplitude, and the period of the wave.

b) What is the formula for a sine wave? – the Period and the Frequency?

c) Draw two sine waves where one is 90 deg phase shifted from the other and label the leading and lagging wave. Why are sine waves important in electronics?

Answer #1

sine wave is important in electronics because it is the only wave which has energy at only one frequency.In electronics and communication circuits deals with different frequencies to carry out operation if our wave is not sine wave then it may have energy at different frequencies also which may lead harmonic diatrotion, noise, crosstalk etc.

please do not give thumbs down right away let me know in comment section if you don't understand it I will help.

5. A pure sine wave cannot convey any information, some change in amplitude or frequency, known as modulation, is required. By combining two sines with slightly different frequencies and wavelengths, the modulated amplitude becomes a sinusoid with phase speed ( modulation speed)Δω/Δk, and called group velocity. Let w1 = w – Δω ; w2=w+ Δω ; k1 = k – Δk; k2= k + Δk show that a. D(x,t) = sin(k1x-w1t) + sin(k2x-w2t)= 2sin(kx-wt)cos(Δk*x-Δω*t) b. group velocity = Δω /...
