Period=360/3 = 120 samples; Pitch=fs/period =16000/120 = 133 Hz Period=225/3 = 75 samples; Pitch=fs/period =10000/75 = 133 Hz Period=195/3 = 65 samples; Pitch=fs/period = 8000/65 = 129 Hz Period=82/2 = 41 samples; Pitch=fs/period = 6000/41 = 146 Hz

Period=365/7 = 52 samples; Pitch=fs/period =16000/52 = 308 Hz Period=275/8 = 34.4 samples; Pitch=fs/period =10000/34.4 = 291 Hz Period=205/7 = 29.3 samples; Pitch=fs/period =8000/29.3 = 273 Hz Period=141/7 = 20.1 samples; Pitch=fs/period =6000/20.1 = 298 Hz
