DimensionalTransmitterBase¶

//
// This transmitter model produces transmissions that use dimensional
// transmission power (that changes over time and/or frequency) in their analog
// representation and the configured modulation.
//
// Allowed expressions for time and frequency coordinates in the gains parameters:
// <pre>
//   s|c|e
//   s|c|e+-quantity
//   s|c|e+-b|d
//   s|c|e+-b|d+-quantity
//   s|c|e+-b|d*number
//   s|c|e+-b|d*number+-quantity
// </pre>
// where s = start, e = end, c = center frequency, b = bandwidth, d = duration. For example: c-b*0.5-1MHz
//
