小弟我已经得到下列程式码
symbol = {'1','2','3','4','5','6','7','8','9','*','0','#'};
lfg = [697 770 852 941]; % Low frequency group
hfg = [1209 1336 1477]; % High frequency group
f = [];
for c=1:4,
for r=1:3,
f = [ f [lfg(c);hfg(r)] ];
end
end
f'
ans =
697 1209
697 1336
697 1477
770 1209
770 1336
770 1477
852 1209
852 1336
852 1477
941 1209
941 1336
941 1477
Fs = 8000; % Sampling frequency 8 kHz
N = 800; % Tones of 100 ms
t = (0:N-1)/Fs; % 800 samples at Fs
pit = 2*pi*t;
tones = zeros(N,size(f,2));
for toneChoice=1:12,
% Generate tone
tones(:,toneChoice) = sum(sin(f(:,toneChoice)*pit))';
% Plot tone
subplot(4,3,toneChoice),plot(t*1e3,tones(:,toneChoice));
title(['Symbol "', symbol{toneChoice},'": [',num2str(f(1,toneChoice)),',',num2str(f(2,toneChoice)),']'])
set(gca, 'Xlim', [0 25]);
ylabel('Amplitude');
if toneChoice>9, xlabel('Time (ms)'); end
end
set(gcf, 'Color', [1 1 1], 'Position', [1 1 1280 1024])
annotation(gcf,'textbox', 'Position',[0.38 0.96 0.45 0.026],...
'EdgeColor',[1 1 1],...
'String', '\bf Time response of each tone of the telephone pad', ...
'FitBoxToText','on');
接下来必须要输入下段程式码才能拨出声音
for i=[5 11 8 6 4 7 7 11 11 11],
p = audioplayer(tones(:,i),Fs);
play(p)
pause(0.5)
end
我的问题是,要如何单纯的输入数字就直接可以拨号
而不用输入一大段程式码才能跑(例如用input...)
请问有哪问高手可以帮忙解决吗
