    thank you so much for these lectures. You are explaning everything baby steps. These are the lectures that uni. prof. lecturers should actually tell like this.

    8:23 - 8:27 , according to my understanding, without separating time factor, the wrong answer will be of amplitude 1 over -3.5 to -1.5.

    If we know axis transformation ... Then we find that 'shortcut' method is just a replica of Method 2( as mentioned in video).
    In that 'shortcut' if we first divide time axis by 2 then add 1.5 .. it would be equivalent operation as discussed in Method 1( as mentioned in video).

    I have found your presentations on Signals and Systems very refreshing. Is there a particular workbook you are using as you are referring to problems in a workbook. Any advice would be greatly appreciated

    What if I take it like this
    x(2(t+3/2))
    Then order of priority of Shift > Scale > Invert
    Then, first shift to the left by 3/2 to get new interval of -2.5 and 1.5
    Finally, scale with 2 to get -1.25 and 0.75
    Not the same answer as yours. What did I do wrong?

    How come negative time shifting make the signal move left ward..
    Also at 13:10
    How come expansion Time scaling made the signal to contract...

    • @Ashish-sp4hw
      @Ashish-sp4hw 6 років тому

      WHEN WE REVERSE A SIGNAL THEN SHIFTING IS DONE IN THE OPPOSITE DIRECTION

    • @zahidfaheem3233
      @zahidfaheem3233 6 років тому

      we're not negative shifting. we're changing the axis from t+3 to t. that's different.

    • @roshanbernard5933
      @roshanbernard5933 4 роки тому

      Even i had the same doubt
      the answer is
      we are not shifting the signal
      we are shifting the time axis
      Delaying the signal corresponds to right shift which is same as advancing the time axis keeping the signal in the same place
      Hope u got it

    Why shouldn't we consider x(2t+3) as x(2(t+3/2)) and perform shifting and scaling

    • @roshanbernard5933
      @roshanbernard5933 4 роки тому

      here the time axis is (2t+3) not t ... so any operation will reflect on (2t+3)

  • @ramneek3732
    @ramneek3732 3 роки тому

    sir ,I could not understand that in second method when there is t+3 then how did we get -4 in x axis , we are adding 3 , it should be -1+3=2, like in shortcut method we are subtracting 3 so -1-3=-4 that's correct

      Multiplying by t entails shortening the waveform, whereas dividing t by some number expands the waveform.

    Sir i think is problem ka solution galat hai kuy ki u says in previous lecture of time scaling ki 2 ko time ke sath multiple karo agar mode of alfa >1 but in 1 st step u divided it

    • @utpalutkarsh7540
      @utpalutkarsh7540 5 років тому

      But to plot the waveform he told to divide each time duration by alpha..compression happens... revise it once again....
