The diagram utilizes two BC548 transistors, more importantly descent results although not as good as RF transistors which provide high performance at wide bandwidth. It also utilizes electret ...

First I’ll tell what you already know. Back in the day, AM broadcasting was king and FM was commercial-free. Things changed in the 1970s as FM grew in popularity. Here we are 40+ years later with many ...

Note: we are working to recover the figures for this article. The process of designing a short-range radio system can be complex and often involves many project tradeoffs (Fig. 1). With a little ...

IN the United States, frequency-modulation has been assigned the wave band 42-50 m.c and at these frequencies, simplification in design and reduction in size of transmitters are of particular ...

The transmission standard for 4K8K satellite broadcasting ISDB-S3 has adopted 16APSK and 32APSK as new modulation schemes. 16APSK has been used for the 4K8K UHDTV broadcasting service in Japan since ...

Broadcast Electronics, under new ownership, will introduce an AM transmitter called AMX, highlighting a compact design and efficiency.

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all radio into channels owned and ...

Puducherry: Puducherry station of All India Radio (AIR) today commissioned a state of art new 10 Kilo Volt transmitter installed at a cost of Rs 2.25 crores. The transmitter of Frequency Modulation ...

An experimental frequency modulated transmitter is described, giving a power output of 1 kW. It was originally designed to operate in the band 40-50 Mc/s, but by the addition of a doubling stage in ...
