Hello,
What's the "bandwidth" in a NE567 chip? What does it define?
i want to build a RF receiver but i don't want to use any custom inductors for tuning; is there's a chip of some kind that can do the tuning for me using some variable resistor or capacitor for that? (freq range from 60 to 300 Mhz should do fine)
i know what the ne567 is, i want to know what they meant by "bandwidth" in the datasheet
i'll be using the chip in a receiver; i'll be sending 2 tones, one is for zero bit and the other for high bit
So what do you suggest i use?

For what?
I don't know what PCM is, so out of the context of our discussion i thought that it was receiving coded ones and zeros
For my receiver, what do you suggest that i use as a signal amplifier?
would simple transistors do just fine or would i need an OP-AMP?
PCM is Pulse Code Modulation - I don't see why he mentioned it?, as you're presumably using ASK as you suggested earlier (post 4).
Thus the need for 1 NE567
And a data bit rate no faster than 5 bps. Maybe faster if the tone is higher Hz
I've never said at which freq i was operating (if you're referring to '200Hz' that was the bandwidth not the frequency)
I was thinking of something around 1KHz; say 1KHz ON and 700Hz OFF
Would that be good for this chip to handle? and does this give me good bps?
