| Question | Answer |
| Period | T = 1/f |
| C (when speed is constant) | c = λ x f |
| x (space) | x = c x t |
| SPL in dB | SPL in dB = 20log (SPL/SPLref) |
| Amplification in dB | 20log (V2/V1) |
| Angle described in radian measure | θ = a/rad |
| 0° | 0° = 0rad |
| 270° | 270° = 3π/2rad |
| 180° | 180° = πrad |
| 90° | 90° = π/2rad |
| 360° | 360° = 2πrad = 0° = 0rad |
| Sine wave formula | y(t) = Asin(2πft+phase symbol) |
| Converting angles into radians | (angle x π)/180 and simplify = radian |
| Fourier Fast Transform |
