31. The covariance function of a sum of sinusoids is itself a sum of sinusoidal functions. 32. Finite-energy non-periodic waveforms can be analyzed into sinusoids by the Fourier transform. 33. The actual frequency of the sinusoid is indicated as " 0 " on the horizontal axis. 34. :Sinusoids are by definition periodic. 35. A is simply the amplitude of the sinusoid and B is the vertical offset from zero. 36. The existence of a forebulge is predicted by the solution to the equations for the sinusoid . 37. Understanding what aliasing does to the individual sinusoids is useful in understanding what happens to their sum. 38. Complex samples of real-valued sinusoids have zero-valued imaginary parts and do exhibit folding. 39. After draining into the liver sinusoids , blood from the liver is drained by the hepatic vein. 40. The main idea of stationary phase methods relies on the cancellation of sinusoids with rapidly varying phase.
