A simple comparator and a Schmitt trigger are shown in Figures 2(a) and _(b). The maximum output voltage, Vmax, can switch between -10 V and ! 10 V for both circuits. The lower and upper trigger levels of the Schmitt trigger are -1 V and 2 V, respectively. a) b) 2V Based on the information given above, sketch the transfer characteristics for both circuits. tola Show that the hysteresis of the Schmitt trigger of Figure 2(b) can be expressed as c) Using the parameters provided above, determine the ratio of R₂/R₁ for the circuit of Figure 2(b). 0 V. in Vhys = Figure 2(a) 2-R₁-Vmax R₁ + R₂ V... in R₂0 +0.6V R₁ Figure 2(b) V
