h-parameter used to find the input and output impedence of the two port network. suppose if u connect a high load at the output port then u should take care that no current from the device will attack the network, to determine that we should know what is the impedance of the circuit.
Answerthe h parameter or the hybrid parameters of a transistor helps us to analyse the amplifying action of transistor for small signal .it is necessary for practical purposes.In generally there are four type of h parameter.these are :h11h12h21h22
h parameters are the two port parameters , a two port parametres has two ports or four terminals two for input and two for output. In general the convention is to take current at both input and output ports into the network.for a linear network (passive elements like current source, voltage source and resistors donot change their value during the performance of circuit), we can write the voltage and current as a linear funcion of input and output parameters. especially these h-parameters are widely used in electronics cirtcuits rather than electrical circuits , the major advantage of these is we need not follow the whole tedious procedure again and again to calculate the input and output parameters just by knowing the h-parameters these values are found by direct substitution , hence one can save a lot of time by using these parameters and we come across different errors while calculation of the output parameters, if we use these h parameters only one confident and neat calculation is sufficient
The output conductance is assumed to tend to infinity and the collector current is assumed to be equal to beta multiplied by the base current.

small signal operations
That's physically impossible!
up to radio frequencies i.e 20-20kh
h parameters
Type your answer here... TO DECREASE THE COMPLEXITY . ANSWER: h parameters are used to analyze small signal behavior o a transistor.
Impedance parameters or Z-parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering to describe the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small signals. They are members of a family of similar parameters used in electronics engineering, other examples being: S-parameters,[1] Y-parameters,[2] H-parameters, T-parameters or ABCD-parameters.[3][4]The Z-parameter matrix for the two-port network is probably the most common. In this case the relationship between the input currents, output voltages and the Z-parameter matrix is given by: .whereFor the general case of an n-port network, it can be stated that
Hull
5h means five times h - the times symbol is not written as it can be confused with a letter 'x': h = 12 → 5h - 2 = 5 x 12 - 2 = 60 - 2 = 58
hfe stands for hybrid parameter, forward current transfer ratio, common emiter configuration.hie stands for hybrid parameter, input impedance, common emiter configuration.hre stands for hybrid parameter, reverse voltage transfer ratio, common emiter configuration.hoe stands for hybrid parameter, output admitance, common emiter configuration.ANSWER: It really stand for signal analysis computations
12 - h = -h + 3 Collect like terms giving 12 - 3 = -h + h ie 9 = 0 Something wrong somewhere!
Harwich - or Hull.
