Connecting Rod used in a reciprocating piston engine connects the piston to the crank or crankshaft. Together with the
crank, they form a simple mechanism that converts linear motion into rotating motion. It was observed that rejection rate of
connecting rod being used in a two-wheeler industry was high. Identifying the root cause of rejection and finding a solution
to reduce or rather eliminate the rejection of connecting rod has been dealt with in this case study.

Filter design is the process of designing a filter (in the sense in which the term is used in signal processing, statistics, and
applied mathematics), often a linear shift-invariant filter, that satisfies a set of requirements, some of which are
contradictory. The purpose is to find a realization of the filter that meets each of the requirements to a sufficient degree to
make it useful. The filter design process can be described as an optimization problem where each requirement contributes
with a term to an error function which should be minimized. Certain parts of the design process can be automated, but
normally an experienced electrical engineer is needed to get a good result.
This paper deals with the design and implementation of IIR filter for wireless communication of a occupied channel. When a
user of mobile occupies a channel, it assigns a range of frequencies for the same channel. For this purpose, we have
designed a IIR filter to select a particular frequency range assigned to a particular channel. In our design, we have designed
the appropriate type of band pass filter to implement this operation.
Keywords: IIR filter, Wireless communication, Band pass filter

With the increasing demand for newer products, subsequent design changes and introduction of newer models, such as in
case of automobile industry, there is a need of quick and reliable method of product design and analysis. The finite element
Analysis (FEA) has gained a lot of popularity in the present scenario as they can be used for quick design and analysis. But
the FE predictions are often called into question as they are, at times, in conflict with test results because of inaccuracies in
FE models which can arise due to use of incorrect modeling of boundary conditions, incorrect modeling of joints, and
difficulties in modeling of damping etc. This paper presents the work that shows the need of correct selection of finite
elements and nodes in order to get a correct prediction of dynamic behavior of the body or machine part under consideration
