| Abstract(in English) | We introduce FVN (Frequency domain variants of Velvet Noise), a new member of TSP (Time Stretched Pulse), which consists of Swept-sine and maximum length sequence for acoustic measurements. FVN enables flexible designing of signal duration, amplitude envelope, and frequency-duration. It also provides a set of orthogonal sequences by allocating different FVNs using a specific orthogonal set of binary sequences. We introduce applications of FVN to acoustic attributes measurement by taking advantages of these FVN properties. |
