The author suggests that the resulting Ehlers Loops are a way to discretionarily predict bullish and bearish moves that are based on the curvature and direction of rotation of motion in the price-volume chart. In the analysis, both price and volume are filtered using high-pass and low-pass filters with the result delivering the desired data wavelengths. In his article in this issue, “Ehlers Loops,” John Ehlers presents some concepts of price and volume relationship to determine if any predictive value can be obtained by the analysis.

We can see that the peakiness of the frequency response curve is quite sharp at the cut-off frequency due to the high quality factor value, Q = 5. If the filters characteristics are given as: Q = 5, and ƒc = 159Hz, design a suitable low pass filter and draw its frequency response.Ĭharacteristics given: R1 = R2, C1 = C2, Q = 5 and ƒc = 159Hzįrom the circuit above we know that for equal resistances and capacitances, the cut-off frequency point, ƒc is given as: Second Order Filter Example No1Ī Second Order Low Pass Filter is to be design around a non-inverting op-amp with equal resistor and capacitor values in its cut-off frequency determining circuit. So for a Butterworth second order low pass filter design the amount of gain would be: 1.586, for a Bessel second order filter design: 1.268, and for a Chebyshev low pass design: 1.234. Then to bring the second order filters -3dB point back to the same position as the 1st order filter’s, we need to add a small amount of gain to the filter. In other words, the corner frequency, ƒr changes position as the order of the filter increases. However, this -3dB cut-off point will be at a different frequency position for second order filters because of the steeper -40dB/decade roll-off rate (blue line). This point is generally referred to as the filters -3dB point and for a first order low pass filter the damping factor will be equal to one, ( ζ = 1 ). We can see from the normalised frequency response curves above for a 1st order filter (red line) that the pass band gain stays flat and level (called maximally flat) until the frequency response reaches the cut-off frequency point when: ƒ = ƒr and the gain of the filter reduces past its corner frequency at 1/√ 2, or 0.7071 of its maximum value. Then for a low pass second order filter, both Q and ζ play a critical role. One final note, when the amount of feedback reaches 4 or more, the filter begins to oscillate by itself at the cut-off frequency point due to the resonance effects, changing the filter into an oscillator. This is when the filter is “critically damped” and occurs when ζ = 0.7071. Then somewhere in between, ζ = 0 and ζ = 2.0, there must be a point where the frequency response is of the correct value, and there is. When ζ = 0, the filters output peaks sharply at the cut-off point resembling a sharp point at which the filter is said to be “underdamped”. When ζ = 1.0 or more (2 is the maximum) the filter becomes what is called “overdamped” with the frequency response showing a long flat curve. The amplitude response of the second order low pass filter varies for different values of damping factor, ζ. The basic configuration for a Sallen-Key second order (two-pole) low pass filter is given as: Second order low pass filters are easy to design and are used extensively in many applications. Second order (two-pole) active filters whether low pass or high pass, are important in Electronics because we can use them to design much higher order filters with very steep roll-off’s and by cascading together first and second order filters, analogue filters with an n th order value, either odd or even can be constructed up to any value, within reason. Most active filters consist of only op-amps, resistors, and capacitors with the cut-off point being achieved by the use of feedback eliminating the need for inductors as used in passive 1st-order filter circuits. The Sallen-Key filter design is one of the most widely known and popular 2nd order filter designs, requiring only a single operational amplifier for the gain control and four passive RC components to accomplish the tuning. All these types of filter designs are available as either: low pass filter, high pass filter, band pass filter and band stop (notch) filter configurations, and being second order filters, all have a 40-dB-per-decade roll-off. Most designs of second order filters are generally named after their inventor with the most common filter types being: Butterworth, Chebyshev, Bessel and Sallen-Key. |
