Resistance Parameters in Terms of Hybrid ParametersAuthor: Leonard Krugman The relationship between the r and h values can be determined by straightforward substitution and the simultaneous solution of equations 7-1 and 7-2, as follows: A. when i2 = 0. Under this condition
If these are solved simultaneously,
B. when i2 = 0. Under this condition equation 7-2A still applies and is solved
C. when i1 = 0. Under this condition
If these are solved simultaneously
D. when i1 = 0. For this relationship equation 7-2B still applies and is solved
E. The current gain As a numerical example of these conversions, the manufacturer's rating sheet for the G.E. type 2N45 specifies the following typical values for the hybrid parameters: hn = 40 ohms, h12 = 2.5 x 10-4, h21 = - .92, h22 = 1.0 x 10-6 mhos. Then
