.. to achived nice performance, in view of it is realized with a cheap microcontroller. This can also be applied to radio frequency band. Software Right image shows the signal flow of internal process. The digitized data blocks are ...
.. how to set the circuitry in Figure 1 for a maximum duty cycle, DMAX, of 0.9. The PWM controller operates at a switching frequency, fS, of 100 kHz. Most PWM controllers cannot reach 100% duty cycle and have a specified dead time. For ...
.. LCD Display How does LC Meter Work? To be able to determine the value of an unknown inductor / capacitor we can use the frequency formula given below. Note that there are three variables that we can work with; f, L and C (f ...
.. it from singing (yes I tried it without the glue:) Other differences The guy at the parts store didn't have any high-frequency rated electrolytes so I got a stack of generic 1000 uF / 35 V radial ones, but they turned out to be ...
.. 100 kHz. Note, however that this circuit is NOT a metal detector, but will detect metal wiring if it conducting ac current. Frequency response is from 50 Hz to about 100 kHz gain being rolled off by the 150 p capacitor, the gain of the ...
.. board you can find the IR-receiver, which in our case is TSOP1738, but you can use any other type of IR-receiver which has frequency of 38 KHz. For output power stage you can use triac TIC206 or TIC216. For loads more than 150W you must ...
.. Transmitter PIC16F630 is the heart of the transmitter used to send IR command to receiver.It also generate 38 KHz carrier frequency. The CR2016 is 3 V battery which is supply for the circuit. When any key not pressed the CPU work in ...
.. switch on the remote and wired my 9 volt battery to it. Test it out! You may have to tinker with the 10 k pot to get the frequency right for the device you are targeting. Adjust the pot while the remote is 'on' and test it ...
.. been reading a lot on how DTMF (Dual Tone Multi Frequency) tones work over the last couple of weeks. I’m sure you’ve noticed that when you press the ...
.. an LT1004-1.2 and reducing R1, the reference bias resistor, to 1k. The 510 Ω and 1.1k resistors are required for high frequency stability; they suppress a 1 MHz oscillation. The 1N5400 diode and 4-amp fuse protect the circuit from ...
