wiki for Guided Tutorial on PSK demodulation

[vempati Sarma]

Hi,

I am trying to learn from the wiki. In the illustrations, taps mentioned for block Decimating FIR filter are -1, 0, 1   simulating difference filter ....These values are not accepted while running the flowgraph. Program seems to expect single value. I am using Gnuradio 3.8.1.0 on Ubuntu 20.04.3LTS. What am i missing?
