Paramatar H (Paramatar Maisuka) a Masana'antu Biyu na Tsakiyar Zafi
Me kowane H Parameters (Hybrid Parameters?)
Hybrid parameters (ko da ake sani h parameters) suna ne 'hybrid' parameters saboda suke amfani da Z parameters, Y parameters, voltage ratio, da current ratios don bayyana yadda voltage da current ta hanyar two port network. H parameters suka taimaka wajen bayyana input-output characteristics of circuits inda zai fi karfi a yi Z ko Y parameters (wanda mafi yawan misali a transistor).
H parameters suna hakuri duka linear characteristics muhimmanci na circuit, saboda haka su zai iya amfani a cikin simulation. Bayanin voltages da current a h parameters zai iya amfani hakan:
Wannan zai iya amfani a matrix form hakan:
Don in fada hadda da h parameters suka taimaka, za a iya neman ideal transformer, inda ba zai iya amfani da Z parameters. Saboda haka, bayanin voltages da current a wannan ideal transformer zai iya amfani hakan,
Saboda an iya tabbatar da voltage a ideal transformer ba zai iya amfani a cikin current, ba zai iya yanayi transformer da Z parameters saboda transformer ba da Z parameters. Duk da haka, ana iya halla shi a kan hybrid parameters (ya'ni h parameters).
An Kofin H Parameters a Two Port Networks
Ba ni short circuit output port of a two port network kamar yadda aka bari a cikin,
Duk da haka, ratio of input voltage to input current, at short circuited output port is:
Wannan shine short circuit input impedance. Duk da haka, ratio of the output current to input current at the short-circuited output port is:
Wannan shine short-circuit current gain of the network. Duk da haka, ba ni open circuit port 1. A nan, ba zai gane input current (I1=0) amma open circuit voltage V1 zai faruwar a port 1, kamar yadda aka bari a cikin:
Duk da haka:
Wannan shine reverse voltage gain saboda, wannan shine ratio of input voltage to the output voltage of the network, amma voltage gain tana bayyana ratio of output voltage to the input voltage of a network.
Duk da haka:
Wannan shine open circuit output admittance.
h Parameter Equivalent Network of Two Port Network
Don in draw h parameter equivalent network of a two port network, first we have to write the equation of voltages and currents using h parameters. These are:
