Page 61: The Different Types Of Digital Filter
Sefram CHAPITRE 5. ADVANCED FEATURES The different types of digital filter The user can choose between 4 different types of digital filters: 5.3.1 Low-pass filter The low-pass filter is a device that exhibits a relatively constant frequency response (fixed gain) at low frequencies and a decreasing gain at frequencies above the cut-off frequency. -
Page 62: Bandpass
Sefram CHAPITRE 5. ADVANCED FEATURES 5.3.3 Bandpass The bandpass filter is a device that demonstrates a relatively constant gain in the passband (band of frequencies between a low cutoff frequency and a high cutoff frequency), increasing gain at frequencies below the low cutoff frequency (40 dB / decade) and decreasing gain at frequencies above the high cutoff frequency (40 dB / decade). -
Page 63: Filter Prototype
Sefram CHAPITRE 5. ADVANCED FEATURES 5.3.5 Filter prototype The filtering performed is infinite impulse response. An infinite impulse response filter (IIR filter) is a type of electronic filter characterized by a response based on the values of the input signal and previous values of the same response. -
Page 64: Butterwork Low-Pass Filter: Bode Diagram
Sefram CHAPITRE 5. ADVANCED FEATURES Butterworth The Butterworth characteristic is probably the most commonly used for signal filtering. This characteristic is said to be "the flattest in frequency". The parameters of this type of filter are arranged so as to achieve the most constant gain possible in the passband and -3 dB attenuation at the cutoff frequency, whatever the filter order. -
Page 65: Butterwork Low-Pass Filter: Impulse Response
Sefram CHAPITRE 5. ADVANCED FEATURES Figure 5.8: Butterwork low-pass filter: Impulse response Chebyshev In contrast to the Butterworth characteristic, the Chebyshev characteristic presents a ripple in the passband. How- ever, it offers better attenuation around the cut-off frequency. The passband ripple is fixed at 0.1 dB. This filter is widely used when ripple is not a problem. -

ADVANCED FEATURES Cheybyshev inversé The Chebyshev type 2 filter, also known as inverse Chebyshev, has monotonic passband attenuation, like the Butterworth filter, and ripples in the stopband. This filter has a better group delay, which means less distortion of complex signals.
-
Page 71: Cold Welding Compensation
Sefram CHAPITRE 5. ADVANCED FEATURES Papoulis The Papoulis filter provides a compromise between the Butterworth filter, which is monotonic but has slower atten- uation, and the Chebyshev filter, which has faster attenuation but has ripple in the passband or stopband. Cold welding compensation When two wires composed of different metals are connected at their ends and one of them is heated, direct current flows through the circuit. - Page 72 Sefram CHAPITRE 5. ADVANCED FEATURES The resulting voltage measured by the voltmeter is equal to V1-V2, that is, it is proportional to the temperature difference between J1 and J2. J2 junction is called reference junction or cold weld. By measuring the temperature of the reference junction using a temperature sensor, it is possible to deduce the temperature of the hot weld.
- Page 73 Sefram CHAPITRE 5. ADVANCED FEATURES No correction No cold welding correction is applied. The temperature returned to the user is the temperature of the thermocouple table associated with the measured voltage. This option can be used if the user wants to measure the temperature difference obtained by two different thermocouples via the use of scripts (calculations between channels).
