CUT-OFF FREQUENCY
Theoretically, the cut-off frequency is the point at the
start of the two finely drawn lines in Fig. G.
In the D-23, the actual characteristics are shown by the
H)
dotted line (Fig. and the broken line (Fig. G). So the
cut-off frequency corresponds to -3dB when the slope
selector is set to -6, or -18dB/oct, and -6dB when it is
set to -12dB/oct.
SLOPE
Slope refers to the amount of attenuation in the fre­
quency response curve per octave (1 octave corresponds
to a doubling, or halving of the frequency).
