    • A system for time-period modulating (TPM) a subcarrier in accordance with the amplitude of an input signal includes generating a ramp signal of constant slope, comparing the ramp signal with the input signal, and resetting the ramp signal when the ramp signal reaches the input signal. Each time the ramp signal is reset, a clock pulse is counted. These clock pulses are counted in cyclic groups of N. After each clock pulse is counted, the then attained count is converted to a value of a sinusoid about some reference. The values for each of N counts define one sinusoidal cycle of the modulated subcarrier. Converting these values to voltage levels produces a sinusoidal stepwave which has a period linearly proportional to the amplitude of the input signal at the time. At a receiver, demodulation of the signal is achieved by squaring each cycle of the TPM signal, and during a predetermined half cycle of each squarewave cycle, generating a ramp signal of constant slope which reaches a voltage level in one half cycle linearly proportional to the period of the TPM cycle. The voltage level attained in each demodulating half cycle is sampled and held until the next demodulating half cycle. In that manner, a step waveform is generated which follows the input signal to the modulator at the transmitter. This system may be used for the L-R signal of a monaural compatible stereophonic transmission system which combines an L+R signal with the TPM L-R signal. The composite is then modulated on a carrier.
    • 根据输入信号的幅度对副载波进行时间周期调制(TPM)的系统包括产生一个斜率斜率的斜坡信号,将斜坡信号与输入信号进行比较,以及当斜坡信号到达时复位斜坡信号 输入信号。 每次斜坡信号复位时,都会对时钟脉冲进行计数。 这些时钟脉冲以N的循环组计数。在对每个时钟脉冲进行计数之后,然后获得的计数被转换成关于一些参考的正弦波的值。 每个N个计数的值定义了调制子载波的一个正弦周期。 将这些值转换为电压电平产生正弦波形,其具有与当时输入信号的幅度成线性比例的周期。 在接收机处,通过对TPM信号的每个周期进行平方,并且在每个方波周期的预定的半周期内,产生一个恒定斜率的斜坡信号,达到一个半周期的电压电平,与 TPM周期。 在每个解调半周期中获得的电压电平被采样并保持到下一个解调半周期。 以这种方式,产生跟随在发射机处的调制器的输入信号的步进波形。 该系统可以用于组合L + R信号与TPM L-R信号的单声道兼容立体声传输系统的L-R信号。 然后将复合物在载体上调制。
