A waveform generator circuit using $$OPAMPs$$ is shown in the figure. It produces a triangular wave at point $$'P'$$ with a peak to peak voltage of $$5V$$ for $${v_1} = 0\,V.$$

If the voltage $${v_1}$$ is made $$+2.5$$ $$V,$$ the voltage waveform at $$'P'$$ will become.

The truth of a monoshot shown in the figure is given in the table below:

Two monoshots, one positive edge triggered and other negative edge triggered, are connected as shown in the figure. The pulse widths of the two monoshot options, $${Q_1}$$ and $${Q_2}$$ are $${T_{O{N_1}}}$$ and $${T_{O{N_2}}}$$ respectively.

The frequency and the duty cycle of the signal at $${Q_1}$$ will respectively be

A general filter circuit is shown in figure

If $${R_1} = {R_2} = {R_A}$$ and $${R_3} = {R_4} = {R_B},$$ the circuit acts as a
