AbstractThe coming of high bit rate PCM and high quality television as common modulation formats has placed stringent bandwidth requirements on telemetry transmitters at S-Band. Two wideband FM transmitters are considered in this report: One for frequency deviations up to ±1 MHz with rates as high as 1.5 MHz; and a new transmitter with up to ±10 MHz deviation and an 8 MHz baseband response. Presented in this report is a new discriminator of the symmetrical Foster-Seeley type. It is capable of 33% peak-to-peak bandwidth and excellent linearity, that allows very wideband requirements to meet in a practical FM feedback transmitter.
