Web30 de dez. de 2024 · A low-pass filter is one way to do it. Due to the interpolation done in the repeat block, you are representing a symbol with 1000 samples, and your sample rate is 2 million samples per second (the samp_rate variable). So your square wave has a frequency of: 2000000 samples second 1 symbol 1000 samples = 2000 symbols second. Or more … Web17 de dez. de 2024 · $\begingroup$ @rclocher3 On-Off Keying.
