Single Op Amp Band Pass Filter

This is a circuit design for a band pass filter. A band pass filter passes a range of frequencies while rejecting frequencies outside the upper and lower limits of the pass band. The range of frequencies to be passed is called the pass band and extends from a point below the center frequency to a point above the center frequency where the output voltage falls about 70% of the output voltage at the center frequency. This is the figure of the circuit.


The filter bandwidth (BW) is the difference between the upper and lower pass band frequencies. The quality factors, or Q of the filter is a measure of the distance between the upper and lower frequency points and is defined as (Center Frequency / BW) so that as the pass band gets narrower around the same center frequency, the Q factor becomes higher. For a single op-amp band pass filter with both capacitors the same value, the Q factor must be greater than the square root of half the gain, so that a gain of 98 would require a Q factor of 7 or more.

LM2678 5 0 on 5Volt Switching Regulator

LM2678-5.0 on 5Volt Switching RegulatorLM2678-5.0 on 5Volt Switching Regulator
This is the circuit diagram of a 5V power regulator based on LM2678 IC. The LM2678 series of regulators are monolithic integrated circuits that provide all the necessary functions required for a switching regulator money and can handle loads up to 5A. The IC has more than 90% efficiency and has to load and line regulation. The LM2678 is available in three fixed output voltages (3.3 V, 5V, 12V) and an adjustable output version. The IC is also filled with a bunch of l features such as thermal shutdown, current limiting and power on / off.

Note:
  • The circuit given here is based on the version LM2678-5.0 which gives an output of 5V.
  • The power supply for the circuit can be anything between 8 to 40V DC.
  • The feedback wiring must be placed as away as possible from the inductor L1.
  • Do not use loads that consume more than 5A.
  • A heat sink is seriously recommended for the IC.

Low Power Wireless Audio Power Amplifier

Battery-Powered portable unit, Suitable for all type Televisions

Using this low-cost project one can reproduce audio from TV without disturbing others. It does not use any wire connection between TV and Loud Speaker. In place of a pair of wires, it uses invisible infra-red light to transmit audio signals from TV to Loud speakers, Without using any lens a range of up to 6 meters is possible. Range can be extended by using lenses and reflectors with IR sensors comprising transmitters and receivers.

Transmitters operation:

IR transmitter uses two-stage transistor amplifier to drive two series-connected IR LEDs. An audio output transformer (T1) is used (in reverse) to couple audio output from TV to the IR transmitter. Transistors Q1 and Q2 amplify the audio signals received from TV through the audio transformer. Low impedance output windings (lower gauge or thicker wires) are used for connection to TV side while high-impedance windings are connected to IR transmitter. This IR transmitter can be powered from a 9V mains adapter or a 9V battery. Red LED (D1) in transmitter circuit functions as a Zener diode (0.65V) as well as supply-on indicator.

Receivers operation:
IR receiver uses popular op-amp IC µA741 and audio-frequency amplifier IC LM386 along with phototransistor L14F1 (Q3) and some discrete components. The sound generated by TV set is transmitted through IR LEDs, received by phototransistor Q3 and fed to pin 2 of IC µA741 (IC1). Its gain can be varied using potmeter P2. The output of IC µA741 is fed to IC LM386 (IC2) via capacitor (C7) and potmeter P3. The sound produced is heard through the receiver’s loudspeaker. Potmeter P3 is used to control the volume of loudspeaker SPKR (8-ohm, 1W).
