Idea04 said:Does an RL low pass and high pass filter need to have the same impedance in the circuit as to the source impedance to work properly. I put an inductor in series with the source with a resistor to ground as the low pass, and a resistor in series with the source with an inductor to ground as a high pass. and there is no filtering of the voltage signal.
Idea04 said:I calculated a transfer function of .002. I measured the signal by having two different multi meters, one for ground and one for output. The voltage gradually increased, but I didn't get any current amplification.
Idea04 said:I'm a bit confused here. To measure the output voltage, frequency and current I have to use an oscilloscope. Why won't a multimeter measure the signals voltage, frequency, and current properly.
Idea04 said:The frequency I am trying to filter is 60Hz, My meter can read to 1 MHz. The meter measures the signal voltage and it gradually rises, but with the components I used I should have a higher current through the output. The calculations show an output current of 1.7 amps but I don't get any output current. So the filter must not be working properly.
An RL Bandpass Filter is an electronic circuit that allows a specific range of frequencies to pass through while attenuating all other frequencies. It is made up of a resistor (R) and an inductor (L) in series, with the output taken across the inductor.
An RL Bandpass Filter works by taking advantage of the impedance properties of resistors and inductors. At low frequencies, the inductor has low impedance, allowing most of the signal to pass through. At high frequencies, the inductor has high impedance, effectively blocking the signal. The resistor acts as a buffer, allowing only the desired frequency range to pass through.
The impedance of an RL Bandpass Filter varies depending on the frequency of the input signal. At the center frequency, the impedance is at its minimum, while at the cutoff frequencies, the impedance is at its maximum. The impedance can be calculated using the formula Z = √(R² + (ωL - 1/ωC)²), where R is the resistance, L is the inductance, C is the capacitance, and ω is the angular frequency.
An RL Bandpass Filter affects voltage signals by allowing only a certain range of frequencies to pass through and attenuating all other frequencies. This results in a filtered output signal with a specific bandwidth and center frequency. The amplitude of the output signal may also be affected, depending on the input signal's frequency and the filter's characteristics.
An RL Bandpass Filter has various applications in electronics, including audio processing, telecommunication systems, and signal analysis. It is commonly used to remove unwanted frequencies from a signal or to extract a specific frequency range from a complex signal. It is also used in tuning circuits and frequency-selective amplifiers.
