[Photo] Audio Notch Filter

At first glance this circuit looks fairly complex, but when broken down, can be divided into high pass and low pass filter secTIons followed by a summing amplifier with a gain of around 20 TImes. Supply rail voltage is +/- 9V DC. The controls may also be adjusted for use as a band stop (notch) filter or band pass filter.

Electric Tea Kettle:

 

Quickly brew the perfect cup of tea or make pour over coffee right at the table with the Electric Tea Kettle. With 1500 watts, this Electric Kettle boils water faster than a microwave, and is safer to use than a stovetop kettle because it automatically turns off when the water reaches a boil. Serving at the table is no problem as the kettle lifts off the base without the cord. Additional features include two water level windows and a pull-lid to make filling and serving easy. 

 

Features:

  •  Thermostat Control – Having a thermostat control allows the kettle to [know" when to shut off. This will prevent damage to the heating element and is an important feature in all modern styles.
  •   Auto shut off/Boil Dry Protection/Fuse â€“ these are three features that are great for protecting the safety of users as well as extending the life of the electric kettle.  The fuse and boil dry protection shut the kettle off if the water gets down below a certain level or if it`s left on for an extended period of time, It doesn`t burn up the kettle.
  • Colors and Designs â€“ Electric kettles come in all shapes, sizes and colors. Finding one that will fit with the kitchen design is actually pretty easy.  Finding one that matches and that has the features you`re looking for can be a bit harder, but with all the choices available and the newer models on the market today, you will be able to find the perfect electric kettle for your kitchen.
  • Savety in Electric- the heating element is typically fully enclosed, with a power rating of 2–3 kW at 220V. In countries with 110V mains electricity, kettles may be less powerful (1–1.5 kW) to avoid drawing too much current and requiring a very thick supply wire.

Application:

Heat the tea thoroughly

Bottle the water/beer

Boil water
