Multiband Bandpass Filters for HF Transceiver (1.30 MHz). Soldering Project KIT

hey what's up guys we're back talking about filters again we've already done high pass and low pass so today we're going to talk about band pass filters an abandoned as frequencies within a certain frequency range and rejects frequencies that are outside of that that's about as simple as it gets so what are its applications well it's used in transmitting and receiving circuits to keep the transmitted or receive signal within the allocated frequency bandwidth they're also used in atmospheric studies and audio applications so you'll see them a lot there now the way we find our frequencies is the same as we did for our low-pass and high-pass filters and we'll come to that in a minute so first of all let's look at our high-pass filter it consists of a sine or you know whatever our wave input is going through a capacitor to the output with a parallel resistor going to ground and the frequenc
