Centre for Development and Advanced Computing (C-DAC) - Education and Training programmes

C-DAC's Education and Training programmes are aimed at creating skilled manpower in the country by providing quality training programmes in the field of Electronics and ICT. This activity started almost two decades ago with a humble beginning of training about 20 students per year, but has today grown to an extent of training more than 5000 students per year. It also grew from just one training centre to about 50 training centres across India and has even made its presence in several countries abroad. In addition to conducting wide range of training programmes in the areas of Information, Communication and Electronics technologies, C-DAC also develops ICT tools and technologies for modern methods of imparting education and training to masses. The Education and Training activities of C-DAC are governed and steered by Academic Council (AC) and Academic Management Committee (AMC).

Presently, C-DAC offers its various training programmes through its own training centres in Bengaluru, Chennai, Hyderabad, Kolkata, Mohali, Mumbai, Noida, Pune and Thiruvananthapuram, and its network of Authorised Training Centres (ATC) spread across the country.

The various activities under the umbrella of C-DAC's Education and Training Programmes are described below:

Post Graduate Diploma Programmes C-DAC conducts two batches of following PGD...		Formal Training Programmes C-DAC also conducts formal training programmes...		Faculty Development Programmes C-DAC conducts advanced faculty training programmes...

Comparision of Active and Passive filters

PASSIVE	ACTIVE
Advantages
No power supply required Can handle large currents and high voltages Very reliable Least number of components for given filter Noise arises from resistances only No bandwidth limitation	No inductors Easier to design High input impedance (Zin), low output impedance (Zout) for minimal loading Can produce high gains Generally easier to tune Small in size and weight
Disadvantages
Inductors large for lower frequencies Some inductors (non-toroidal) may require shielding Limited standard sizes, often requiring variable inductors and therefore tuning Low tolerance inductors (1-2%) very expensive Must be designed with consideration to input and output loading Generally not amenable to miniaturization No power gain possible No voltage gain	Power supply required Susceptible to inter-modulation, oscillations Susceptible to parasitic from dc output offset voltage and input bias currents Op amp gain bandwidth constrained Op amp slew rate constrained Can require many components
