A band-pass filter will only pass frequencies within a certain range. Finally, a notch filter will reject frequencies within a specific range, and pass all frequencies outside of that range.
Frequency is measured in cycles per second or Hertz. For example, human hearing reaches up to around kHz thousand times per second. A Bluetooth or WiFi radio signal at the other extreme oscillates at a frequency of 2. Low-pass RC filter The simplest low-pass filter is made using only a resistor and a capacitor and is appropriately called an RC filter.
Figure 9 — Low-pass RC filter In this circuit, the signal goes into R1 and the filtered output is taken off the node between R1 and C1. A capacitor passes high frequencies and blocks low frequencies.
So in a low-pass RC filter, low frequencies will see C1 as very high impedance open-circuit , and high-frequencies will see the capacitor as low impedance to ground.
In a low-pass RC filter, all the high frequencies go through C1 to ground.
This essentially removes the high-frequency components, whereas low frequencies are passed on to the output. The cutoff frequency is the frequency at which the filter begins filtering. For a low-pass filter, frequencies below the cutoff frequency are passed, and those above the cutoff frequency are rejected.
No filter is perfect though, and there will be some frequencies around the cutoff frequency that are passed to the output highly attenuated reduced.
The capacitor is still a high impedance to low frequencies and a low impedance to high frequencies. Figure 10 — High-pass RC filter The cutoff frequency follows the exact same equation as the low-pass RC filter, except that now frequencies above this cutoff frequency are passed.
Hence, the name high-pass filter. An inductor functions just the opposite from a capacitor.
An inductor passes low frequencies, and blocks high frequencies. For an RC filter the resistor simply sets the cutoff frequency.
If there is no resistor, the cutoff frequency becomes infinite — meaning every frequency is passed and no filtering at all occurs. For a low-pass LC filter, in addition to the capacitor sending high frequencies to ground, high frequencies are also blocked by the inductor from reaching the output. Transistor Find the transistor symbol in the schematic symbols overview.
This is probably the hardest of the basic electronic components to understand.
A simple way is to look at the transistor as a switch controlled by an electrical signal. If you put about 0.
Note that this is true for NPN transistors. There are also other types, but worry about these later. A bit of current on the base produces a current of maybe times more depending on the transistor through the Collector and Emitter. We can use this effect to build amplifiers. Inductor Find the inductor symbol in the schematic symbols overview.
Inductors are a bit weird. They are often used in filters. See his response at the end of that article. Integrated Circuit Find the integrated circuit symbol in the schematic symbols overview.
