Low pass filter circuit 10KHz using uA741
      This be the circuit filters 10KHz low size frequencies s use IC op-amp the highly popular number uA741. By this circuit convenients for to apply to input and output of the circuit changes analog signal be digital or the circuit changes digital signal be digital. In sound system of digital for synthetic the voice or music give for make wave form output the smooth. And press the noise that happen at output. When small-sized signal was managed with decrypt linear the size is 8 bit. Note: More low pass filter circuits see below:: • Cheap car subwoofer filter circuits • …
2 Light controlled tone generator circuits
These circuits is used to control audio with light. In simple transduction And the change of light. To control the tone.,we is recommended that three circuits, each circuits consists of a simple device. Suitable for studying the performance of optical sensors is LDR. Tone Generator Control with light using IC 555 This the Tone Generator circuit that interesting because of can control the sound has with the light. By use the integrated circuit NE555 be pillar equipment , which perform produce sound frequency in model Astable Multi vibrator or pulse generator. And use 25 ohm small-sized loudspeakers. For the equipment …
Strength meter circuit using IC741
This is strength meter circuit that it can test we strong, by catch 2 metals. From that time squeeze meet. It will make LED stick bright arrange prevent according to one's ability of squeezing the metal. The work of the circuit uses our body is formed lead the electricity changes to reach in the circuit.
Musical Chime Generator Using UA741 oscillator
This is a musical generator that uses bandpass filter circuit with ua741 op-amp as act converts a sound signal in multiple feedback patterns. When connected the voltage input from a rhythm generator with a short pulse , makes it ring in natural resonance frequency. As the output oscillations vanish suddenly and resemble percussion or strum sounds naturally. The higher the Q the longer the decay time constant. The VR1 is used to adjusts a Q value. The fo is 1/(185 x 1000 x C). The high frequency resonances resemble chimes, lower frequencies sound like calves or bongos. Several circuits, all …
Universal mono preamplifier using ic lm741
