    Change frequency of PCB

    Hi, I have some speakers I love, they have a PCB RF reciever inside. I bought more speakers but they are a different frequency.. I'd like to change them so they all match but have no idea what I am doing. Can you help?

    Increase clock frequency

    Hi, I’m working on a logisim project for university. I need to increase the clock frequency to 16 Hz, but the frequency must be set in the options to 1 Hz. How can I increase the frequency using only a circuit? Thanks for the help.

    Logisim - clock

    Hi, I’m working on a logisim project for university. I need to increase the clock frequency to 8/16 Hz, but the frequency must be set in the options to 1 Hz. How can I increase the frequency using only a circuit? Thanks for the help.

    why in this article baud rate is considered as bit period or bit rate?

    I have read this article where I want to save a small question that made questionned my understanding: 1-first question: in this article baude rate/bit period, how can he takes the bit period as the baud rate. in my understanding, bit rate=(1/bit period) = baude rate* number of bits in 1 baud...

    IR infra red frequency convertor

    hi everyone, not sure if this is even possible, maybe someone knows of a way. I have a IR blaster that sends at 38kHz and a device that has a 37kHz infra red system. is there a IR convertor \ relay that can make the receiving device (cable set top box) accept the commands of the sending...

    Sine wave generator with variable frequency (1Hz-500kHz)

    I thought at first to use a VCO, but I didn't found any that generates a sine wave with 500Khz. So I thought to use a microcontroller, like Atmel o Arduino, but it's really difficult to create a PWM greater than 4MHz. Do you know any other way to generate a sine wave?

    VHF oscillator circuit w/ large frequency range and change according to capacitance value

    Hello, It's my first post. I'm new in electronics fields. I'm french and my english is not very good, excuse me. I want to make a VHF oscillator(~ 30 MHz) that his frequency can change with the value of the capacitance. I found in an another post the RF2506 which seems to works but it's...

    Frequency control in a circuit

    Hello! My goal is to power an electromagnetic coil. In this circuit I want to use sine waves at a low Hz (below 10 Hz). Im using a signal generator but it does not have enough power for my coil. How can I hook up my signal generator to a AC power supply to regulate the frequency? Or should I try...
