| reciprocal value of the open-loop gain response at the phase crossover angular frequency|
SEE: Figure 9.
Note 1 to entry: In logarithmic representation of the open-loop gain response the value of the gain margin Gm may be read as negative logarithm −lgGm at the phase crossover angular frequency. Gm herein results from Gm = |G0(jωπ)|–1 (see Figure 10).
Note 2 to entry: This entry was numbered 351-25-07 in IEC 60050-351:2006.
