Description
<p>The PAM/ASK Generator converts analog input signals to Pulse Amplitude Modulated (PAM) output signals or digital data to Amplitude Shift Keyed (ASK) output signals.
In PAM, an analog input signal is sampled using either natural or flattop sampling, and a pulse with a height proportional to the input signal amplitude is generated at each sample point. In ASK, a tone is output for a "1" and no tone is will be the output for a "0" at the input. PAM and ASK are not true digital signals, since both convey information as modified analog signals rather than as a digital code.
Using the PAM/ASK Generator, students gain an understanding of the principles of PAM and ASK generation. The relationship between the sampling rate and highest frequency present in the modulating signal, and the
effects of bandwidth and pulse duration are also investigated.
