Low pass filter

Just need to check the answer : ( I dont know the answer myself so an explaination will be appreciated. )


A signal at 1Khz is sampled at 1500 samples/sec and passed thru a low pass filter having a cut off 800 Hz . What is output frequency .

Thanks
Regards
 

Low pass filter

Looks like a signal processing chapter 1 problem. Did you miss the lecture?
Check how sampling image/alias frequencies are calculated.
