Sine Wave To TTL Converter

Sine Wave To TTL Converter is a series that we can use to change the sine wave signal with a pulse shape with the same frequency with TTL logic level that we are ready to use in coding the data digitally . The series of Sine Wave To TTL Converter can be used to convert sine wave signal to form a TTL of frequency 100KHz to 80MHz at the level of 100mV - 2V. The series of Sine Wave To TTL Converter uses a 5VDC voltage source. The series of Sine Wave To TTL Converter was built from transistor T1 gets base bias from R3, R4 and R5. If the series Sine Wave Converter This TTL To get the input sine signal with a minimum level of 100mV, the circuit Sine Wave To TTL Converter This will generate an output signal with TTL level square wave.

The series of Sine Wave To TTL Converter has input + impedance - 50 Ohm which is set using the R6. To change the value of the input impedance converter circuit Sine Wave To this TTL can be set via the R6 with a maximum value of 300 ohms.

Audio Frequency Generator Circuit

Audio Frequency Generator or often known by AFG is a device electronics used to generate signals with audio frequency range. Audio Frequency Generator (AFG) in the market there are many variant, from the analog to the digital . Even the assembly also exists, in principle, AFG is the frequency generator with an audio range. Here is one set of Audio Frequency Generator (AFG) which can be a reference if you want to make a series of Audio Frequency Generator (AFG) . The series of Audio Frequency Generator (AFG) is to use IC L8038 as a signal generator it.

AFG

The series of Audio Frequency Generator (AFG) above has three output waveform that is, sine, square and triangle directly from the IC L8038. IC CD4066 and IC circuit Cd4017 a configuration circuit for waveform selector that can be set by pressing SW1. To adjust the working frequency is set by potentiometer R2.

Triangular Wave Generators

Triangular Wave Generators or Generating Triangle Waves in this article consists of 2 main parts. The main part is a series of non-inverting Schmitt triger by integrator circuit A1 and built by A2. Output Non-inverting circuit Schmitt triger on the Triangular Wave Generators or Generating Triangle Waves is a wave of box used for the driver integrator A2. Integrator is given a square wave input will output a triangle wave and used for feedback (feedback to a series of non-inverting Schmitt triger circuit A1 in Triangular Wave Generators or Generating Triangle Waves is thus a series of non-inverting Schmitt triger A1 will provide input into integrator repeated again and this continues.

The working principle circuit Triangular Wave Generators or Generating Triangle Waves at the first time is when the non-inverting Schmitt triger A1 gets first supply will provide logic high or low. When output is non-inverting Schmitt triger A1 A2 logic low, the integrator will output a high ramp wave, while the output at non-inverting Schmitt triger high A1 integrator output ramp down form of waves. Where A2 is the output integrator circuit input Non-inverting Schmitt triger A1 so that the incident will be repeated and the triangular wave generator running.

Timer 555 Schematic

Simple Timer With 555 is one example of a simple timer and can be applied to electronic equipment. With 555 Timer Simple series takes advantage of the mode of the IC monostable multivibrator 555. With the relay output control circuit can be used to control equipment with AC voltage source. With 555 Timer Simple circuit can work with source voltage of 5 - 12VDC depending on the relay used. In order to use Simple Timer With this 555 can be started by pressing the switch S1 to start the process of timing. In the relay there are 2 options that is normaly Close connection (NC) and normaly open (NO).

The duration of the timing circuit 555 Simple Timer With RC configuration is determined by the VR 1 MOhm and C 10uF. Active timer duration can be calculated with the formula T = 1.1 RC where T (seconds), R (Ohm) and C (farad). To get more accurate results R and C components referred to in the formula should use good quality components, namely C of tantalum material and R with the quality of 1%.

Radio Frequency Generator Schematic

Radio Frequency Generator (RFG) is a tool used to generate the RF frequency. In the experimental modulation technique Radio Frequency Generator (RFG) is used as a carrier signal generator (carrier). The series of Radio Frequency Generator (RFG) can generate frequencies from 150KHz - 12 MHz. The series of Radio Frequency Generator (RFG) has been equipped generator modulation signal (information signal) that can be used to adjust the position of switch SW2. The series of Radio Frequency Generator (RFG) is also equipped with output level control via potensio VR1 and the output impedance selector selector with SW1. The series of Radio Frequency Generator (RFG) is also equipped with selector selector frequency band consisting of 5 range. For more details can be seen from the picture series of Radio Frequency Generator (RFG) follows.

The series of Radio Frequency Generator (RFG) above has 5 frequency range 150 KHz - 500 KHz, 350 KHz - 1 MHz, 750 KHz - 2.25 MHz, 1.6 MHz - 5 MHz and 3.5 MHz - 12 MHz. Selection of frequency range tersbut done by adjusting the position of selector switch SW3. To adjust the working frequency Radio Frequency Generator (RFG) is done by adjusting the lever variable capacitor (Varco), C1 and C2 are connected parallel.
