Mini function generator circuit using ICL8038
Mini Projects
This is the Mini function generator circuit using ICL8038 IC-number. (Precision Waveform Generator/ Voltage Controlled Oscillator) It will generate output 3 the waveform, include Sine wave signal,the triangle, and square wave signals. The output of this circuit is quite realistic in the waveform. And we will suggest a 2 model include (1.) the basic model (2.) the improved performance model,we can customize even more. If you interested, don’t wait. Let’s see it below! The Basic circuit diagram function generator using ICL8038 Figure 1 The basic circuit of function generator using ICL8038 The Basic characteristics of the circuit with a few …
FM transmitter circuit without coil
Basic Circuits
This is FM transmitter circuit without Coil,using inverter digital IC as main and controlled frequency is precise by crystal. Figure 1 the circuit diagram In Figure 1 is RF oscillator circuit which use a inverter IC1/2 and ceramic crystal filter 10.7 MHz to use drive IC1/4 – IC1/6 by through IC1/3. When inverter in parallel form this impedance output is low thus they can drive directly an antenna. When output of IC1/4 – IC1/6 are square wave which have much more internal harmonic. The harmonic number 9 of frequency 10.7 MHz (96.3 MHz) will take place at the center of …
Long range fm transmitter circuit,2W(2 km) 88-108 MHz frequency VHF
Mini Projects
This is long range fm transmitter circuit in VHF range. As Figure 1 Sonar with up to 2 watts, when used with a supply voltage of about 24V. In the case of applications typically do not want a high transmission. This circuit requires only one power supply 9V Only. If used voltage level of the power supply more than 10V. We need a heat sink to transistor-Q2, To prevent this transistor overheating. Figure 1 the schematic diagram of 2W(2 km) 88-108 MHz frequency VHF/FM transmitter First, try entering the power supply to the transmitter with the 9 volts battery rectangular …
