A first-order system with a time constant equal to 10 ms is subjected to a sinusoidal forcing with an input amplitude equal to 8 V. When the input forcing frequency equals 100 rad/s, the output amplitude is 5.66 V; when the input forcing frequency equals 1000 rad/s, the output amplitude is.8 V. Determine
the magnitude ratio for the 100 rad/s forcing case,
the roll-off slope in dB/decade for the ωτ=1 to ωτ=10 decade
the phase lag in degrees for the 100 rad/s forcing case
