Python how to plot graph sine wave

Question

I have this signal :

from math import*
Fs=8000
f=500
sample=16
a=[0]*sample
for n in range(sample):
    a[n]=sin(2*pi*f*n/Fs)

How can I plot a

Answer 1

import numpy as np
import matplotlib.pyplot as plt

F = 5.e2          # No. of cycles per second, F = 500 Hz
T = 2.e-3         # Time period, T = 2 ms
Fs = 50.e3        # No. of samples per second, Fs = 50 kHz
Ts = 1./Fs        # Sampling interval, Ts = 20 us
N = int(T/Ts)     # No. of samples for 2 ms, N = 100

t = np.linspace(0, T, N)
signal = np.sin(2*np.pi*F*t)

plt.plot(t, signal)
plt.xlabel('Time (s)')
plt.ylabel('Voltage (V)')
plt.show()
