    SMPS vs TRANSFORMER PS

    OK Well OK. SMPS setup makes the circuit much more stable providing a closed loop system where the exact monitoring of the output is done and the error (difference in output) is fed back to the input to higher.lower voltage. Using SMPS reuires the use of a frequency which is much higher than...

    TV reception problem

    Interesting Well this is quite an interesting post. Surely enough this could nto happen if the neighbour connects the DVD to TV using composite. There are scart to composite adapters that can be used to connect composite to the Auxiliary of the set. The problem of transmission can only be...
