The x[n] is apssed in recrussive loopp called y[n]=y[N-1]+x[n]
1)i dont know what the term 'M' means.
2)In the image what represents that its is 440hx wave
Hi,
On the presumption that this screenshot is from the following video: **broken link removed**
1) 'M' is the delay (see timepoint 12:17 of the video)
2) In the image, the LHS waveform represents a single 440 Hertz wave. The numbers along the x-axis represent values of M, the delay. All of this is explained at timepoint 14:08 and onwards, in the video.
bhuvaneshnick said: i thought its samples rather than be a delay,and how would you say its 440 hz wave
M represents both delay (see timepoint 12:17 of the video) as well as number of samples (this equivalence is mentioned at timepoint 13:48 of the video "M-tap delay generates an M-sample periodicity")

i am watching that again and again.On 14.00 f=1/TM=>f=1/22.6us*100=>440hz
So,what we do is sin(2*pi*440) ,instead here it is written as sin(2*pi*n/00) for 1<n<100 and its is passed it recursion(y[n]=y[N-1]+x[n]).The number written on x-axis denoting M not time.then how we say its 440 hz.
