HC Deb 21 April 1947 vol 436 c616
98. Mr. William Shepherd

asked the Postmaster-General if he has given consideration to the advantages of pulse width over frequency modulation; and whether he has given any lead to set manufacturers as a result.

The Assistant Postmaster-General (Mr. Burke)

Consideration has been given to the respective merits of frequency modulation and other types of modulation, including pulse modulation, for broadcasting on very short waves. At the present stage of technical development it is considered that frequency-modulated broadcasting offers the best prospects and the Government have approved the British Broadcasting Corporation's plans for the development of this system. Radio manufacturers have been advised accordingly.
