For each band, let the constant, , represent the frequency change (in Hz/minute), divided by the maximum frequency (in Hz). Then the rates of change for the three bands will be 125, 500 and 2,000, respectively. The times (in minutes) to traverse the three frequency bands areThe required maximum constant rates of frequency change for the three bands are therefore 8.55 Hz per minute, 34.2 Hz per minute and 137 Hz per minute, respectively. The minimum times of traverse of the bands are 8.2 min, 10.9 min and 10.9 min, respectively.按照的規(guī)定,假設(shè)將整個(gè)頻段分為55至125,125至500,500至2000Hz三個(gè)頻段.在每一頻段,令頻率的變化率與該段頻段的最高頻率之比值為k，則三個(gè)頻段的頻率變化率分別為125k、500k及2000k，各頻段經(jīng)歷的時(shí)間分別為（125-55）/（125k）、（500-125）/（500k）和（2000-500）/（2000k）。因?yàn)榭偟膾呙钑r(shí)間為30分鐘，因此可求出k=0.0687/分鐘。三個(gè)頻段的頻率變化率分別為8.55Hz/分鐘、34.2Hz/分鐘和137Hz/分鐘，經(jīng)過三個(gè)頻段的時(shí)間分別為8.2 分鐘、10.9 分鐘和10.9分鐘.4.2.
