4. A circuit is shown to the left. a; :1 1kg 5m a. Is this an example of positive feedback or negative feedback? If the circuit is an amplifier, what is the gain and is it inverting or noninverting? Ifthe circuit is a comparator calculate the threshold voltage. The input signal (shown in red) is a sine wave with a frequency of 100 Hz and a peak-to-peak voltage of 2.0 V. Draw the output signal on the same graph. Voltagzl (V) \\l\\) h
