Hi guys,
I have a circuit for AM generation using BF494 (beta = 160) and and an IFT (455 KHz) etc. The problem is that I don't know how we arrive at the resistor and capacitor values in this circuit. Can anyone help me withe design of this circuit. Vcc = 12 V. I am attaching the circuit schematic. I tested the circuit with values given in the image attached, it is working very well. When I took the 1Mohm from circuit still the AM circuit works. I wanted explanation for the working and design of this circuit.
I am also inserting the design procedure currently I am having with the image , please check it for any errors and correct me.
TIA
