Please help me.
I'm learning processing of signals from book Allen B. Downey.
I cannot running function Chirp:
#---------------
import thinkdsp
signal=thinkdsp.Chirp()
wave=signal.make_wave()

The interpretator say me this fucking string, that I did not understand \:( :
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/helloworld/python/signal_analysis/task/thinkdsp.py", line 1240, in make_wave
ys = self.evaluate(ts)
File "/home/helloworld/python/signal_analysis/task/thinkdsp.py", line 1529, in evaluate
dts = np.diff(ts, append=ts[-1])
TypeError: diff() got an unexpected keyword argument 'append'
>>> signal=impulses(signal)
