IC 4049 Square wave oscillator generator

We can bring the inverter CMOS digital IC is CD4049 Hex Inverting Buffer IC, to design the Square wave oscillator generator circuit diagram or Simple Pulse Generator circuits, to a lot circuit been simplified.
The circuit we use a little equipment, just add a resistor and capacitor are the only one,It uses less energy. The output frequency is relatively constant, the rate of change in frequency of the power supply voltage is less. The pulse generators can also produce a 50% duty cycle square wave. The ICs in the circuit number CD4069,TC4069,LM4069. The frequency determined by R1 and C1 is F = 1 / (1.39xRxC). The power supply used DC 3V-12Volt.

Pulse generator control frequency by digital IC

This circuit uses frequency pulse generator, its continuity or Astable Multi Vibrator circuit. By the number 555 is compatible with IC1 VR1, R1, R2, and CT. The value of CT in the selection of the electronic switch circuit IC2 number 4066.Electronic switch with 4 built-in IC 2.
The control the electrical contact switches (ON), The input voltage is positive or logic “1″ to the control pin. The pin 13, 5, 6 or 12.
If the control pin to ground.Switch is turned off (OFF). Switches each, to separate the work independently, not be sorted.
And incoming (IN) and output (OUT) can be interchangeable.
It is therefore reasonable to switch the value of C values.With the input signal to the logic of digital circuits,The binary code is “0″ to “1″.
When I switch on the control of either a logic “1″, the electrical contact of the switch, then tap it. A capacitor connected to the pin switch is connected to pins 2 and 6 of IC1. To determine the frequency with VR1, R1 and R2.
Sometimes it may be the control logic “1″ rather than a pin. Makes the capacitor is connected in parallel, rather than an option. The capacity will be increased. The introduction of the C together. Circuit can reduce or increase the value of R1, R2. Or for convenience, you can adjust the resistance of VR1 at all. Signal pulse is sent out to pin 3 of IC1′s output signal. To enter the circuit, such as count circuit, divide, or be connected to the speaker. To make a sound or signal.

Basic pulse generator using IC 1458

This is astable multivibrator circuit or Square-Wave Oscillator
or basic pulse generator it use op-amp IC-1458 is main parts and a few parts.
By have Vsat value size as same as with power supply voltage. The frequency Output set by value R1
and C1.
Frequency Oscillator output = 1/(2R1.C1.ln3)
The C1 capacitor to change capacitance per frequency value 1uF = 8Hz,0.1uF = 50Hz,0.01uF=700Hz,0.001uF = 6KHz.
The IC1b use to boost up current output and to buffer load.
IC 1458 use IC other number = RC4558 = LF353 =etc.
