Tested all the resistors and noted 2 resistors` readings were out compared to the other channel (i. e.1. 2Kohm vs 2. 2 kohm). Based on the color codes, should be 2. 2kohm. THought I spotted the problem, repl the "1. 2kohms" with new 2. 2 kohms but the.... -
The LM1036 is a DC controlled tone (bass/treble), volume and balance circuit for stereo applications in car radio, TV and audio systems. An additional control input allows loudness compensation to be simply effected. Four control inputs provide control of.... -
Many times we needed to use a simple circuit of preamplifier, with few components and facility of made. This circuit use a opamp. the Motorola, TCA5550, that contains a double amplifier, as outputs for the adjust of volume, balance, treble and bass. These.... -
This circuit is design, in order to is heard the voice above the music. Useful for DJ, for small radio stations, for statements above the music, in shops etc. Also we can him use in applications that we want to handle some unit with our voice. As it has the.... -
Other one unit of graphic EQ. five bands. The basic difference with the other circuits is, that I use instead of IC, transistor and the power supply, go up in +/- 24V DC, ensuring low distortion and bigger margins of overloading. With switch S1, we can.... -
The EQ-2 it is a circuit of graphic equalizer 6 band of regulation. Each band is regulated from the potesometers RV1-6, that are, for better optical indicate of regulations, Fader. This does not mean that we cannot him replace with simply potesometer. In the.... -
In order to obtain a good audio reproduction at different listening levels, a different tone-controls setting should be necessary to suit the well known behaviour of the human ear. In fact, the human ear sensitivity varies in a non-linear manner through the.... -

This unique property makes the ˜paraphase configuration of interest if only treble or bass needs to be adjusted - it is not possible to adjust both at the same time! Essentially, it s the difference in setting of the tone controls that determines the slope.... -
An audio tone control combines both a Base control and a treble control in the same circuit. Tone controls are found on lower-end audio gear because it saves both front panel space on the unit and only requires one control knob, instead of two separate.... -
This topic continues the coverage of audio tone controls. The first entry started with a Passive Tone Control circuit using different RC filter configurations and introduced an active filter. The second entry showed a fully designed 2-Band Active Tone.... -
This topic continues from the more general Passive Tone Control circuit, which begins using only passive filters. This circuit follows the previous design, although the component values are different and in an alternate configuration. An audio tone control.... -
A difficult problem in the design of conventional stereo tone controls is obtaining synchronous travel of the potentiometers. Even a slight error in synchrony can cause phase and amplitude differences between the two channels. Moreover, linear potentiometers.... -

Use the 48V (60V) DC feedback electric current which is provided by the phone feedback line as the working energy of the electronic doorbell is very economical and practical. Now I introduce one kind of two-tone doorbell circuit with out battery. The circuit.... -
This is single op-amp tone control circuit. This circuit is a hybrid low-pass, high pass and one-pole circuits with attenuation and gain. This circuit is the.... -
The LM1036 is a DC controlled tone (bass/treble), volume and balance circuit which can be applied in car radio, TV and audio systems. Loudness compensation to.... -
Tone control circuit is an electronic circuit which is designed to manipulate the tone of audio signal. Tone of audio signal is analog to color in light. We.... -
Achieves high carrier and modulation suppression by using closely matched diodes and providing R1 for amplitude adjustment and coaxial line for phase adjustment. R2 provides slight amplitude adjustment. -W. H. Ellis, Diode Quad Modulator Suppresses Carrier.... -
Permits monitoring local VHF FM repeater for calls from friends without having to listen to chatter of others or to repeater noise. Operation is similar to that of Motorola paging units in which special tone is transmitted to disable squelch of receiver.... -
When the carrier level is adequate to switch the cross-coupled pair of differential amplifiers, the modulation signal, which has been applied to the gate, will be switched at the carrier rate, between the collector loads. When switching occurs, it will....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -

The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
