What is h parameters transistor?
Hybrid Parameters are the values which is used to find FREQUENCY RESPONSE of a low frequency transistors. you may have doubt like why we are using only H-PARAMETERS why not HYBRID-PI models because..., h-parameters values are constant at low frequency moreover, at low frequency transition model we have assumed that the response of transistor to changes of input current or input voltage is instantaneous this is the reason why we had neglected shunt capacitances . as there were no shunt capacitances there is no chance of using hybrid-pi model. i hope you got answer for your question
What is the importance of H-parameter of transistor amplifier?
In transistors, current gain plays a significant role. In h parameters, one of the parameters is hfe which is current gain. It is easier if the parameters chosen represent some significant properties of the device. Some other parameters of importance in transistors are input resistance hie and output resistance 1/hoe.So it makes sense to analyse transistors with h parameters.
Advantages of hybrid modulation over digital modulation?

What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
Relation between h parameters and r parameters of transistor?
the hybrid equivalent or the h-parameter are used for small signal, low freq. applications. i) h-parameters can be measured easily ii) they are more independent of each other like frequency and operating point iii) h-parameters are real no. at audio frequencies. iv) they are = value of input impedance and output admittance adikan f UK u
Why hybrid parameters are called hybrid?
Hybrid parameters are called so, because the parameters have different units. In Z- parameters, all the parameters have units of ohms and in Y- parameters, all parameters have Siemens as units. But in hybrid parameters, we have both ohms and Siemens as units. The other way it is called hybrid is, the independent variables are the input current and output voltage.

Why are h parameters known as hybrid parameters?
Every linear circuit having input and output terminals can be analysed by four parameters- 1 measured in ohms; - 1 measured in mho; - 2 are dimensionless are called h parameters. Hybrid means 'mixed'. Since these parameters have mixed dimensions, they are also called HYBRID PARAMETERS. These parameters are used to specify a transisitor performance conveniently for small voltages and currents in a particular circuit.
Why h parameters are used?
They are one standardized way of describing the characteristics of bipolar transistors.

What was a Hybrid Radio?
One form of hybrid radio, appearing in the late 1950s, used valves (vacuum tubes) and transistors together. Early transistors worked fine at audio frequencies, and were much more efficient, using much less battery power. They could not perform at radio frequencies, however. Vacuum tubes had been used at radio frequencies for many years, but the push to miniaturise them led to lower performance. Even the subminiature types (about the diameter of a cigarette) still used a lot of battery power to operate. The hybrid radio used valves in the radio frequency end (usually three) and transistors in the audio end (usually two). This design made best use of the advantages of valves and transistors. Transistor development was rapid, and all-transistor radios appeared soon after hybrid sets were marketed. They were only available as battery portables. Hybrid sets are among the rarest of mass-produced radios.

What are 3 advantages of transisters?
I will assume you mean "transistors". Compared to their predecessors (vacuum tubes), transistors:* Are faster * Use less current * Use less space Note that all of these advantages get even more pronounced in the case of integrated circuits (which also contain transistors).
