Method Detail

parity_pitch

static int parity_pitch(int pitch_index)

Compute parity bit for first 6 MSBs

Parameters:

pitch_index - input : index for which parity is computed

Returns:

parity bit (XOR of 6 MSB bits)

check_parity_pitch

static int check_parity_pitch(int pitch_index,
                              int parity)

Check parity of index with transmitted parity
