lines of MATLAB code that will do this scaling operation in general. There are two approaches here: a. Mathematical: derive a formula for β from the formula for the frequency response of the BPF. Then use MATLAB to evaluate this closed-form expression for β. b.
If you have any questions not explained well by the existing comments, write back to tell me what chunk of code is not well explained/commented. This project is designed in MATLAB and I have tested it on MATLAB 2009 and MATLAB 2014 and it works fine on both of them.

When any key is pressed, the sinusoids of the corresponding row and column frequencies, shown in Fig. 1, are generated and summed. Hence the name dual tone.

Dual-Tone Multi-Frequency is a decoding method used in the telephony to code numerical digits by means of sound signals in the audio band. Full documentation about the matlab code is available on the following link: http://dev.emcelettronica.com/signal-generation-with-matlab-example-of-dtmf-in-telephony
DTMF Generator. DTMF signaling uses two tones to represent each key on the touch pad.

Digital Half Toning - Ordered Dithering - MATLAB Code Bayer/ Ulichney December 23, 2016 Digital Half-toning is a technique to convert the gray scale / color image (in the range 0-255) to binary images (in the range 0-1) that is useful for printing (especially black and white printers).
if we have 16 subcarriers let us dedicate r1,r2,r3 and r4 as PRC or peak reduction carriers and transmit on x1:x12 so when x1:x12 summation creates a peak, a combination from r1,r2,r3 and r4 creates an anti peak but i need matlab code for tone reservation algorithm in OFDM if anybody knows plz reply me Digital Half Toning - Ordered Dithering - MATLAB Code Bayer/ Ulichney December 23, 2016 Digital Half-toning is a technique to convert the gray scale / color image (in the range 0-255) to binary images (in the range 0-1) that is useful for printing (especially black and white printers). function testaudio() sampleRate = 44100; duration = 0.5; freqs = [100 200 300 400 500 600 700 800 900 1000 1100 1200]; [signal t] = generateTone(freqs, sampleRate, duration); sound(signal, sampleRate); %generates a tone (pure or complex) function [y t] = generateTone(freqs, sampleRate, duration) timeSamples = duration * sampleRate; t = linspace(0, duration, timeSamples); y = zeros(size(t)); env = generateEnvelope(t); for i=1:length(freqs) temp = env.*sin(2*pi*freqs(i)*t); y = y + temp; end Fs = 1000; %# Samples per second toneFreq = 50; %# Tone frequency, in Hertz nSeconds = 2; %# Duration of the sound y = sin(linspace(0, nSeconds*toneFreq*2*pi, round(nSeconds*Fs))); When played at 1 kHz using the SOUND function, this vector will generate a 50 Hz tone for 2 seconds: sound(y, Fs); %# Play sound at sampling rate Fs 2014-09-01 · The tone generated by the button in position (k,j) is obtained by superimposing the two fundamental tones with frequencies fr(k) and fc(j). y1 = sin(2*pi*fr(k)*t); y2 = sin(2*pi*fc(j)*t); y = (y1 + y2)/2; If your computer is equipped with a sound card, the statement sound(y,Fs) plays the tone.
