1000 Threads found on edaboard.com: How To Amplify A Signal
I have developed a sine wave generator with DDS chip AD9833.
AD9833 has an output signal of 0,6 Vpp. I use AD9833 to generate a sine wave at a frequency of 50 Hz and use a microcontroller to change the frequency (40-400Hz).
The signal is amplified up to 4Vpp and with a digital potentiometer I control the amplitude.
how to (...)

Power is the condition where the voltage is dominant. A carrier is dominant while the message has less power not because of the voltage level but because it less dominant. You might still have a carrier but the change in voltage produced by the message is not there. The carrier is always there and it's power is the voltage level. The power of the m
