One of the circuit blocks you can use to generate the triangular waveform is the integrator. an integrator integrates the input signal. for the circuit given below express v1 in terms of r1, c1, v0, and t, assuming v0 is not varying with time. what is the slope of this voltage ramp? you may also assume that capacitor c1 has 0v across it at time t = 0. hint: you will have to apply kcl, and use that the current flowing through a capacitor is given by i = c dv dt .
