What does the term/value 'ΔK' represents in an equation of Mason's Gain Formula?

a. Path Factor

b. Forward Path Transmittance of kth path

c. Loop Gain

d. Graph Determinant

ANSWER: Path Factor

Explanation:

Mason's Gain Formula is used to evaluate an overall transmittance (gain), which can be expressed as,

T = k=1∑n PK ΔK / Δ

where, Pk = forward path transmittance of kth path

Δ = graph determinant comprising closed loop transmittances & mutual interactions between non-touching loops.

ΔK = path factor consisting of all isolated closed loops from the forward path in the graph.
