1)The convolution between two signals is always
  

2)Rxy[r] and Ryx[r] represent the cross-correlation between two signals x[n] and y[n] and that of their reversed order. Then which one of the following is correct
  

3)In the setup of experiment 5(a), if signal x(r) is symmetric and signal h(r) is asymmetric then their cross-correlation and convolution would be
  

4)For any signal, the value of auto-correlation at any lag is
  

5)When can be the cross-correlation between two signals be symmetric about zero lag?
  

6)The value of auto-correlation function of a signal at zero lag represents
  

7)If (t1, t2) and (t3, t4) be the start & end point pairs of two time-limited signals x(t) and h(t), respectively. The start & end point pairs of convolution and cross-correlation of these signals would be
  

8)The correlation of a signal with a shifted version of itself is known as
  

9)The value of auto-correlation can never be bigger than it is at
