Tsukure Mad Labs Band Pass Filter

Every analog designer’s nightmare would be to deal with noise in his circuit. When it comes to switching circuits or Audio amplifiers or frequency signal circuits there is a very good chance for the circuit to be affected by noise signals. Out of the many ways to remove noise from a circuit, the most used one is called a Filter Circuit. As the name suggests, this circuit will filter out the unwanted signals (noise) from the actual signal. There are many types of filter circuit, but the most commonly used and efficient one is the Band Pass Filter which can be easily constructed using a pair of resistor and capacitors. So in this tutorial, we will learn about this Band Pass filter, the theory behind it and how it can be used in rractical circuits.

Let's Get Started!

Below you will find a list of bits to gather before hand, followed by a detailed schematic. Using a breadboard lay out the components and connect them together as shown. Alternatively you can purchase this module from our shop and simply solder the components in the places indicated on the quality assured printed circuit boards provided.


What You Need...


1 104 (100nF / 0.1uF) Capacitor (Ceramic)
1 471 (470pF / 0.47nF) Capacitor (Ceramic)
2 PCB Mount 2-Pin Screw Terminal Block Connector (Other)
1 1K
[ Brown, Black, Black, Brown ]
Resistor (0.25 Watt)
1 47K
[ Yellow, Violet, Black, Red ]
Resistor (0.25 Watt)

NB: Any resistor colour codes specified relate to 5 band resistor codes, the 5th band has not been shown intentionally. The 5th band indicates the resistor tolerence, we use only the highest tolerence resistors in our products.
