Hi, i've been able to make an FSK circuit and its working good.....
now i've to send it in the air....... for wireless communication.... now the question is that if my FSK signal's low freq is 19MHz and hi freq is 20MHz (refer to the image i've attached, here i've kept a big difference in the hi and lo level freq so that it can be easily seen)....... now i've 2 questions:
1- do i simply have to put a power amplifier whose input would be the circuit in the image and then attach an antenna to the output of the power amp as 20MHz will cover atleast 10meters.... and i dont need much range..... plz reply refer to the image named 'power amp.jpg'
2- what does the power amplifier boost?? current or voltage?? plz guide me and if possible make a sketch of the block digram .....
