Active Filters Manufacturer,Supplier and Exporter in India
Product Code : EL-AET-1466
Jlab Export is a leading Active Filters Manufacturer,and suppliers in India
Active Filters (code EL-AET-1466) is an analog electronics training board for studying the characteristics of four operational-amplifier filters — low-pass, high-pass, band-pass and notch. The filters are built around four op-amp ICs powered by an internal IC-regulated ±12 V supply, and the band-pass section covers the band between its 100 Hz and 1 kHz cut-off frequencies. Jain Laboratory Instruments Pvt Ltd (JLab) builds the board at its Ambala works in India.

How Does It Compare with the JLab Passive Filters Board?
| Model | Filters | Circuit and supply | Experiment |
|---|---|---|---|
| This board (EL-AET-1466) | Low-pass, high-pass, band-pass and notch | Four op-amp ICs; internal ±12 V DC IC-regulated supply | Characteristics of each active filter |
| Passive Filters | Constant-K low-pass, high-pass and band-pass; m-derived low-pass and high-pass | Passive filter sections built into the board | Filter constants and cut-off frequency of each filter |
Choose the Active Filters board when the syllabus covers op-amp filter circuits, including a notch filter; choose the Passive Filters board for classical constant-K and m-derived network sections. Both boards use an external audio frequency generator and an AC millivoltmeter for the measurements.
What Is the Active Filters Board Used For?
An active filter combines an operational amplifier with resistors and capacitors, so it can shape a frequency response without inductors and present a high input impedance and a low output impedance to the circuits around it — as the kilohm input and tens-of-ohms output figures above show. With a sine signal from the generator applied at a series of frequencies and the output read on the millivoltmeter, students plot the response of each section, find its cut-off points and slope, and see how sharply the notch section rejects the band around its centre frequency. It is a standard practical in analog circuits and linear integrated circuits courses at diploma, BSc electronics and engineering level.

Frequently Asked Questions
What is the difference between active and passive filters?
A passive filter uses only resistors, capacitors and inductors, so it cannot provide power gain and its response changes with the load connected to it. An active filter adds an amplifier, usually an op amp, which gives buffering and can give gain, avoids bulky inductors at audio frequencies, and needs a DC supply to run.
What does a cut-off slope in dB per decade mean?
It is how fast the output falls outside the pass band: the number of decibels the output drops for every tenfold change in frequency beyond the cut-off point. A steeper slope separates wanted and unwanted frequencies more sharply.
What is a notch filter used for?
A notch filter rejects a narrow band of frequencies around its notch frequency while passing frequencies on either side. The same idea is used to remove mains hum or a single interfering tone from a signal.
What other apparatus is needed?
A decade audio frequency generator and an AC millivoltmeter. JLab’s Audio Signal Generator and A.C. Milli Voltmeter Type are separate items, linked below, that can be quoted on the same enquiry.
What information is needed for an export quotation?
The number of boards, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling instructions, and the tender reference when there is one.
Who manufactures the Active Filters board?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electronics trainers and laboratory instruments, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The Active Filters board is made at JLab’s own works, not purchased from a trader, so engineering colleges, polytechnics, dealers and importers deal with the maker itself; each board is visually inspected before dispatch, and repeat orders and spares are handled by the same works. JLab exports worldwide and ships to buyers in every region — for example South Korea in East Asia, Egypt in North Africa, Kenya in East Africa, Denmark in Northern Europe and Colombia in South America. Tender details are on the JLab lab tenders page.
