AM transmitter ?????

[yadiw]

hello to all.. I had a project;
but I dont know how to do it..
1 message signal with oscillator (2 kHz)
1 carrier wave with oscillator (600 kHz)
with a analog multiplier AD633..
do you have any circuits about it..
thank you;;-)

If what exactly is to be accomplished is clear, the issue will be better defined to form a view and suggest.

Feed the 2KHZ into one input, the 600KHZ into the other, take the output via a bandpass filter tuned to 600KHZ. Voila!, you have AM.

If the 2kHz were centered around zero volts then you would not have AM. You would have DSB - double side band suppressed carrier. To get AM you have to make sure the audio signal is offset from zero so it never crosses through zero,

hey but i must connected them with AD633 multiplier in isis ...thanks for answers and your time;
