IIR Filter design in digital signal processing

IIR Filter design Concept of filter design:     "Analog filters are designed using analog components like resistors (R), inductance (L) and capacitors (C).while digital filters are implemented using difference equations& can be done using C or assembly language we can easily change the algorithm so we can easily change the filter characteristics according to our requirement".

How GMSK Modulation Technique works in GSM?

How Mobile Network works with GMSK  Modulation Technique ? Answer: "Gaussian Minimum Shift Keying or Gaussian filtered Minimum Shift Keying, GMSK is the form of modulation with no phase discontinuities & it is used for data transmission due to efficient spectrum usage." GMSK Introduction : MSK modulation

E-Shape Microstrip Patch Antenna for Pervasive Wireless Communication at 14GHz (Ku Band)

E-Shape Microstrip Patch Antenna for Pervasive  Wireless Communication at 14GHz (Ku Band): "Changing the shape of antenna will result in changed Radiation pattern so as to improve or locate required area changes in the conductive part of antenna should be done".

Bit padding in Synchronous TDM :

Bit padding in Synchronous TDM : "Till now we have assumed that the data rate of all the channels is the same ". But practically it won't so. We will have to multiplex channels having different data rates.

why we are using impulse signal for analysis of any control system?

why we are using impulse signal for analysis of any control system? Impulse signal spectrum      "In signal processing, the impulse response, or impulse response function, of a dynamic system is its output when presented with a brief input signal, called an impulse".
