I had designed a Differential Amplifier AM Modulator previously and found that I should make some correction to the circuit as an improvement. The differential amplifier AM (Amplitude Modulation) is also called "Long-Tailed Pair" modula…
I wrote about AM modulator using MC1496 modulator for AM generation four year ago in 2022. While the circuit works as I have demonstrated in video which is provided below, there is room for improvements. Here I want to write down note on how to i…
Dive into the world of analog electronics with a comprehensive look at the MC1496 AM modulator. This article provides an in-depth guide to building and understanding an AM modulator circuit using the versatile MC1496 integrated circuit, perfect fo…
Emitter modulator is one of many ways you can construct a modulator. It is classified as an active modulator because a BJT transistor is used in its construction. Passive modulators uses diodes for its operation. Here an emitter modulator design is …
Since my soldering iron got damaged I could not de-solder components from the Compact Fluorescent Lamp (CFL) bulb circuit board today. I have to buy a new one, but until then I learned more about the CLF bulb circuit components. As part of learn…
Double Sideband-Suppressed Carrier (DSB-SC) Amplitude Modulation (AM) is a key technique in communication systems, often used for efficient signal transmission. Demodulating a DSB-SC AM signal can be challenging, but one effective method is cohere…
I came across a AM demodulation circuit that uses an emitter follower circuit before the envelope detector. I wanted to check whether using emitter follower would improve the demodulation circuit. I know that in electronics circuit, the input imped…
