Find the value of $${R^1}$$ in the circuit of fig. For generating sinusoidal Oscillations. Find the frequency of oscillations.

The $${f_T}$$ of a BJT is related to its $${g_{m,}}\,\,{C_\pi }$$ and $${C_\mu }$$ as follows

In a series regulated power supply circuit, the voltage gain A_v of the ‘pass’ transistor satisfies the condition:

Compression in PCM refers to relative compression of
