Dear all, I have actually built an AM circuit in real life to combine high frequency carrier sine wave (200kHz) and signal wave of triangle wave at (3kHz), and the output is on my oscillioscope which I am happy about. However, when I try to resonant the wave on my oscillioscope using LC tank, the output get very nasty and unreadable and even if I actually used a high frequency op-amp (TL072), it does not really have much gain and current amplification plus the waveform becomes distorted. So, I really believe that my Wave shown in the oscillioscope is of very high impendence and I needed to buffer it to feed into LC tank to give beautiful AM signal. May I know if there is a way to increase the output current (lower impendence) of the signal I shown above. It is made up of 200kHz sine wave to form the overall jagged triangle I would really appreciate any help because I have spent quite a lot of time on this haha
Thank you for reading and have a nice day !!
