Stereo Encoder works but the transmitted music comes out with noise. Another important feature of this IC is that the transmission frequency can be set using a 4 channel DIP switch. Capacitors C2 and C16 sets the roll-off point of datasheeh low pass filter.
If you are building the above stereo encoder and have trouble finding some of the components like BH and 7. The multimeter should show a reading equal to the supply voltage. Placing 10K stereo potentiometer on audio inputs can help eliminate that problem, although it is not necessary to achieve a good sound quality.
What can be done to eliminate that noise? I am pretty sure hobbyists will agree.
BH Datasheet, PDF – Alldatasheet
What can I do to eliminate that distortion? Lowering the bh of incoming audio source should do it.
Bulk Buy Discounts Order bh or more and enjoy the savings. If there any further costs bbh during the bh or repair process, we will ask you bh take responsibility for those as well.
Any way such a capacitor is not at all a necessity here and the circuit will work perfectly even if the capacitor at pin 9 is omitted.
L1 is a plastic former with 6mm adjustable ferrite slug similar to the figure shown http: This includes preparing your items, performing quality checks, and packing for shipment. Lowering the volume of incoming audio source should do it.

Resistor R4 and capacitor C9 connected in series between the collector and base of Q1 provides further filtering. MPX stream that is generated by BH contains both stereo and mono audio signals. It can be connected to any type bh stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other bh system to transmit stereo sound with excellent clarity throughout your home, office, yard bh camp ground.
Capacitor C10 works as a high frequency filter while R7 is meant for isolation. Now move the positive lead of the multimeter to the junction of R5 and R6 and adjust the slug ferrite core of L1 so that the multimeter reads 2V. BH can be supplied with 6 – 15V voltage, consumes only around 25mA while providing very sound quality and improved 40dB channel separation.
It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can bh1471 used for connecting various sensors and connectors. Audio coax cable highly recommended. Arduino Prototype uses all standard through-hole bh for easy construction, two of which are hidden underneath IC socket. Stereo Encoder bh but the transmitted music comes out distorted.
The link between pin 12 and dataheet 7 should be between pin 12 and pin 8. If power supply is being used make sure that all the diodes on the rectifier are bypassed with a 10n capacitors daasheet that your voltage supply is gh filtered with bh least uF capacitor.
The composite output signal at pin 5 is applied to the junction of R6 and R7 though a network comprising of components C4, C5, C6 and R1.
Please read the descriptions carefully and clearly before purchasing. Stereo Encoder works but the transmitted music comes out distorted.
Resistor R3 serves as the collector load for the transistor Q1. Once that is done turn off transmitter and disconnect its audio inputs.
So put this in a good looking box and start selling. However, you are bh for paying the return shipping fees and the repair fees. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.
Capacitor C8 connected between collector and base of Q1 provides additional high frequency filtering. Total Estimated Delivery Time. All warranty datashewt will be rejected after days from shipment.
This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. Once that is done turn off transmitter and disconnect its audio inputs.
Firstly set the frequency of transmission using the DIP switch. The meter is a perfect bj1417 to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.
The darlington transistor Q1 is driven by the output of the pin7 and the transistor applies a control datashert on the varicap diode through resistor R5, R6 and R7.
