00:01 There is a triangular input signal so let's denote the input signal with way in and with in so that you could understand what does it mean so this is the input signal and the input signal is a triangular wave all right so and let me draw the input signal here in x -axis i have the time and the time is is in milliseconds in the y -axis i have the amplitude all right now if time is equal to zero milliseconds then the amplitude of the wave is minus 10 words it is given all right so it means the wave would start from here so this is one milliseconds this is two millisecond this is three millisecond and this is four milliseconds so at two milliseconds the amplitude of the wave is plus 10 so this is minus 10 and the amplitude it after two milliseconds should be plus 10 so it means that our graph should be like it should start from here it should cross the xx is here and it should touch this point at 2 milliseconds so at 0 milliseconds it is at minus 10 at 2 milliseconds it is at plus 10 and again at 4 milliseconds it is again minus 10 all right so the graph should be like it should come here and it should cross this already and it should be like this one all right now let me label the circuit components this is 0 milliseconds this is 1 millisecond this is 2 milliseconds this is 3 milliseconds and this is 4 milliseconds so after 4 milliseconds it is again minus 10 at 2 millisecond it is plus 10 so i hope you are understanding so this is the input graph so this is the graph for our input all right and the circuit given to us is we have an operational amplifier here with this this is the positive input this is the negative input all right with the negative input we have a capacitor connected and a resistor connected and this is touch with the output and here in the input we have given the input signal the input signal is the triangular wave so we have given the input here and this positive is ground this is a resistor r and this is a capacitor c sorry i have done a small mistake here sorry for the inconvenience my ear student a small mistake here let me write again for you because this negative terminal of this operational amplifier is not directly connected with the input all right so it would be like this signal negative signal yeah this is connect this is connected with the capacitor and with the resistor are and this whole thing is connected with the output so this is actually the circuit diagram so let's label the circuit components now this is capacitor this is resistor here we have output and here we have input signal that is we in and input signal is this triangular wave all right my dear students so now, in the first part, we have to recognize that what this circuit does.

04:53 So the aim of the this circuit is this circuit is actually an operational amp profile that is op amp differentiator.

05:09 So what will, what does it do? it differentiates the input signal.

05:16 So the aim of this circuit is to differentiate the input signal.

05:20 Signal so that's why it is called operational amplifier differentiator all right now so what would be the output the output signal of this amplifier is given by the formula the output would be equal to r times c the product of r nc then the time derivative of the input signal all right so this is the output of this triangular wave.

05:58 Now the output of this triangular wave will give us what kind of signal? it will give us a signal.

06:08 So better i should draw the signal on this...
