I'm pretty sure i didn't understand one word u wrote.
I speak and read Electronics Technical english. which language do you speak and read?
I repeated the important details in the datasheets for the ICs.
(quote)Also i was asking about the capacitors in the circuits i attached.
Didn't you ask about your missing supply bypass capacitors that are talked about and shown in the datasheets?
The capacitors in your receiver circuit are not needed. The output is digital. Low when it receives a signal and high when it doesn't. The 100k resistor is not needed since the TSOP already has a resistor at its output.
The datasheet for the TSOP IR receiver shows that its automatic-gain-control reduces the gain when continuous IR is received because it might be interference from a compact fluorescent light bulb. The TSOP is designed for remote controls that have bursts of data separated with pauses then the TSOP keeps its gain high so that it is very sensitive.
It is all in the datasheets so you should read them.
