Functions Documentation
function plp_dwt_max_level
uint32_t plp_dwt_max_level(
uint32_t sig_len,
uint32_t wavelet_len
)

function plp_dwt_dec_len
uint32_t plp_dwt_dec_len(
uint32_t sig_len,
uint32_t wavelet_len,
uint32_t level
)
Calculates decomposition output length given a level.
Parameters:
- sig_len length of input signal
