2.1 Discrete-Time Signals: Time-Domain Representation Here,n-th sample is given by x[n=xa()l=nr=xa(nT),n=.,-2,-1,0,1,. The spacing T between two consecutive samples is called the sampling interval or sampling period Reciprocal of sampling interval T,denoted as Fr,is called the sampling frequency: F=1/T§2.1 Discrete-Time Signals: Time-Domain Representation • Here, n-th sample is given by x[n]=xa(t)| t=nT=xa(nT), n=…,-2,-1,0,1,… • The spacing T between two consecutive samples is called the sampling interval or sampling period • Reciprocal of sampling interval T, denoted as FT , is called the sampling frequency: FT=1/T
