Function generator ranging from 0.1 Hz to 20 MHz can be easily built using MAX038 integrated circuit chip. Here is the most simple implementation of high frequency sine wave generator, and you can easily modify it to generate square wave, or triangle waveform. Here is the schematic diagram of the circuit: In the …
Read MoreTo test some electronic systems such as RF communication, filter, or audio we often need random noise source. This article shows the circuit that generates an RMS amplitude regulated noise source with selectable bandwidth. This circuit is suitable for wide range of application since it has 1 KHz to 5 MHz decade ranges selectable bandwidth …
Read MoreAn excellent tone burst generator can be made using 556 Dual Timer. We can connect the first half as a one-shot and the second half as an oscillator. The oscillator turns on because the pulse established by the one-shot turns, allowing a burst to be generated. Here is the circuit diagram: [Source: Philips …
Read MoreWhat is A pH Meter? A pH meter is actually a precise voltmeter that measures the generated voltage of a pH electrodes. The requirement of such meter is high input impedance and has the gain of voltage-pH conversion. The standard pH probe generate voltage about 59 mV per pH, so all we …
Read MoreThis is example of a simple inverter that can be used to power fluorescent lamp and a small strobe. This circuit will produce over 400VDC from a 12 VDC, 2.5 A power supply or marine battery or an auto. This circuit is very simple because it does not require custom transformers or coils. Also all …
Read MoreThis temperature controller employs an LM135/235/335 temperature sensor, can be used to keep small environment warm or hot. Here is the schematic diagram: LM311 is used as comparator, to detect if the voltage at sensor pin (the inverting input) goes higher than the reference pin (the non-inverting pin). If this condition is …
