Now the rectangular wave is Ok.</p> <p>Hui </p> http://www.k-wave.org/forum/topic/how-to-produce-periodic-rectangular-wave-by-toneburst-class%ef%bc%9f#post-6264 Thu, 18 Jan 2018 14:12:55 +0000 Bradley Treeby 6264@http://www.k-wave.org/forum/ <p>Hi Hui,</p> <p>You do not need to use a k-Wave function to create the input signal (it can be anything). You could try looking at the MATLAB function <code>square</code>.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/how-to-produce-periodic-rectangular-wave-by-toneburst-class%ef%bc%9f#post-6257 Sun, 14 Jan 2018 15:56:40 +0000 HuiLIN 6257@http://www.k-wave.org/forum/ <p>Dear Dr. Treeby and Dr. Cox:</p> <p> I want to produce periodic rectangular wave to simulate the ionoacoustic propagation of the scanning proton pencil irradiation.<br /> I plan to build up based on the example_us_defining_transducer.m. However, I found all the ‘us’ examples are only based on the toneBurst class to produce the periodic input_signal. The input signal is Sinusoidal.<br /> Now my questions are:<br /> Whether there are other classes I can use to produce the periodic rectangular wave, even triangular wave? If there is only toneBurst class, how I can obtain the needed wave?<br /> And how I simulate the different Duty cycles of rectangular wave? i.e. different signal time and its interval time?<br /> Thank your reply in advance.</p> <p>Hui </p>
