1)in Exp 3(a) CTFS-CTFT , for a periodic signal with period 2.5 s, the spectral content at 0.4 Hz corresponds to which harmonic in the CTFS harmonic plot?
  
2)For a periodic signal which one of the following statements characterize the relationship between number of harmonics within a fixed frequency band and time period of the signal ?
  
3)In exp 3(e) CTFT-DTFT, for what value of the sampling rate the impulse-sampled version of continuous time signal x(t) matches with the given discrete time signal x[n] ?
  
4)In exp 3(c), what is the frequency of the spectral component corresponding to 4th harmonic for the corresponding normalized frequency components when the period is set to 5 ?
  
5)A continuous-time signal x(t) has a Fourier Transform X(w). The Fourier transform of the time shifted signal x(t+p) would be given by
  
6)If a signal is discrete in one domain(time/frequency), then its equivalent representation in the other domain would be
  
7)"The total energy of all discrete time n is equal to the total energy in one fundamental frequency" - this statement is better known as
