Webb11 mars 2024 · A particularly simple kind of wave, the sine wave, is illustrated in figure 1.2. This has the mathematical form. (1.2.1) h ( x) = h 0 sin ( 2 π x / λ) where h is the displacement (which can be either longitudinal or transverse), h 0 is the maximum displacement, also called the amplitude of the wave, and λ is the wavelength. Webb(8.67) defines a signal that comprises a sine wave of frequency 1.25 Hz, together with two further sine wave components of frequencies of 10 Hz and 0.3125 Hz that only exist 3 to 11.2 s and 12.8 to 22.4 s respectively. Normally distributed random noise with a standard deviation of 2 is also added.
Peak values can be calculated from RMS values from the above formula, which implies VP = VRMS × √ 2, assuming the source is a pure sine wave. Thus the peak value of the mains voltage in the USA is about 120 × √ 2, or about 170 volts. The peak-to-peak voltage, being double this, is about 340 volts.
