Square wave generator similar to dsp.SineWave

8 visualizzazioni (ultimi 30 giorni)
I know squarewave() function, but I would like to know is there an equivalent system object square wave generator, just like dsp.SineWave so I can generate 1024 samples per loop for demodulation purposes in streaming processing of audio signals.
Thanks

is this for use in simulink ? if so the repeating pattern generator can be used.

I actually have implemented stream processing where the entire process is real time based, contained within a while loop, currently using sine wave but I just want to produce square wave instead in matlab, not simulink.

Please take a look at audioOscillator in Audio System Toolbox, which can generate sine, square, and sawtooth waveforms.

Glad to hear that helped!
As for visualizing the response of graphicEQ, if the visualize() doesn't work for you, then you may want to use coeffs() to extract the filter coefficients and then plot the response using a standard approach, such as the following:
% Create and configure the equalizer
g = graphicEQ;
g.Gains = 6*randn(size(g.Gains)); % random gains in dB
% Extract the coefficients
[B,A] = coeffs(g);
% Compute the response using the SOS argument format for coefficients
[h,f] = freqz([B;ones(1,size(B,2));A]',4096,g.SampleRate);
% Plot magnitude over frequency and customize appearance
hp = plot(f,db(abs(h)));
hp.Parent.XScale = 'log';
hp.Parent.XLim = [20, 20e3];
xlabel('Frequency (Hz)')
ylabel('Response (dB)')
grid('on')

Thanks Gabriele! the solution worked like a charm!
