Q. Illustrate Transformer coupling?
In this method the primary winding of the transformer acts as a collector load and the secondary winding transfers the a.c. output signal directly to the base of the next stage. Such a coupling increases the overall circuit gain and the level of the inter stage impedance matching. However transformers with broad frequency response are very expensive and hence, this type of coupling is restricted mostly to the power amplifiers where efficient impedance matching is a critical requirement for maximum power transfer and efficiency. The amplifiers using this coupling scheme are called Transformer coupled amplifiers.
(a) A universal shift register can shift in both the left-to-right and right-to-left directions, and it has parallel-load capability. Draw a circuit for such a shift register.
