WebSep 15, 2024 · Generate some signals (in Python) We can generate signals with three parameters, 1) signal duration, sampling rate, and frequencies. As we are storing the signals as a sequence of numbers, first, we need the number of data points of the signal. This can be done by multiplying the signal duration with the sampling rate. WebPlot the signal for 2 seconds. Test Cases: # sampling rate sr = 100 # sampling interval ts = 1.0/sr t = np.arange(0,2,ts) freq = 5. x = 3*np.sin(2*np.pi*freq*t + 3) freq = 2 x += 2*np.sin(2*np.pi*freq*t - 2) plt.figure(figsize = (8, 6)) plt.plot(t, x, 'r') plt.ylabel('Amplitude') plt.xlabel('Time (s)') plt.show() WebAug 26, 2024 · The sin () function takes a single argument, the angle in radians.

WebJan 15, 2024 · We can take a simple sinusoid (i.e., “carrier wave”) and modulate (i.e., change) the phase to communicate information to a receiver. Binary phase-shift keying (BPSK) BPSK is the simplest mechanism to communicate information by manipulating the phase of a carrier wave. The phase of a transmitted wave is changed between two states.
