Re: Generate 100Khz amplitude modulated signal

Thank you everybody for your responses and lively discussion.

It seems after reading your posts that my needs require more than software-based solution or to use something other than the raspberry pi.

Best,
Rani

Re: Generate 100Khz amplitude modulated signal

Thank you joan for your reply. I want to be able to program a signal which is composed of a carrier frequency between 40-100 kHz which is amplitude modulated at 5-40hz. the signal should be generated by the RP and then it is supplied to an amplifier that drives the transducer. what I would like to k...

Re: Generate 100Khz amplitude modulated signal

I am trying to drive a transducer maybe through the GPIO pins on the raspberry.

Generate 100Khz amplitude modulated signal

Hi,

I want to use a RP4 to generate a 100Khz sine wave which is modulated by another 5Hz sine wave.

Is this possible? and how should I get started in programming this ( I am most comfortable with python.)

Thank you
